The headset 10 further comprises structures and functional blocks enabling it to operate as an ANC headset that provides the acoustic output signals SO such that ambient sound SA is counteracted in a way that reduces the level of ambient sound SA arriving at the ears 5, 6 while still allowing desired sound, such as music or speech received in the audio input signals Si, to pass through.

The electroacoustic transducer 23 is adapted to radiate an acoustic output signal So into the front cavity 27 and thus provide it to the ear 5.
重叠投影区域290允许光束200通过每个反射器。
The overlapping projected areas 290 allow the light beam 200 to pass each of the reflectors.
至少一个反射器210的反射中心轴250可以与至少另一个反射器210的投影区域290相交，从而允许光束200多次通过至少一个反射器210。
The reflection centre axis 250 of at least one of the reflectors 210 may intersect the projected area 290 of at least one other of the reflectors 210, thereby allowing the light beam 200 to pass at least one of the reflectors 210 multiple times.
在根据上述第一示例实施例的光学系统100’-1(或其变型)中，至少一个反射器210被配置成可在调整方向220上移动。
In an optical system 100'-1 according to a first example embodiment (or the variant thereof) described above, at least one of the reflectors 210 is configured so as to be movable in an adjustment direction 220.
优选地，调整方向220平行于反射器210a、210b、210c和210d中至少一个的反射中心轴(250a、250b、250c和250d)。
Preferably, the adjustment direction 220 is parallel to the reflection center axis (250a, 250b, 250c and 250d) of the at least one of the reflectors 210a, 210b, 210c and 210d.
替代地，调整方向220可以相对于反射中心轴倾斜(例如，正交)。
Alternatively, the adjustment direction 220 may be inclined (for example, orthogonal) with respect to the reflection center axis.
如果调整方向220被选择为平行于反射中心轴250，则光束200的长度的连续调整是可能的。
If the adjustment direction 220 is chosen so as to be parallel to the reflection center axis 250, continuous adjustment of the length of the light beam 200 may be possible.
然而，如果调整方向220被选择成与反射中心轴250正交，则光束200的长度可以以离散的步长变化。
If, however, the adjustment direction 220 is chosen so as to be orthogonal to the reflection center axis 250, the length of the light beam 200 may be varied in discrete steps.
也就是说，在后一种情形中，与至少一个特定反射器210相关联的光束200的通过次数可以变化。
That is, in the latter case, the number of passes of the light beam 200 associated with at least one particular reflector 210 may be varied.
在根据本文描述的第一实施例的光学系统100’-1(或其变型)中，光源20可以被配置成提供具有将使包括光学系统100’-1(或100’-1*)的OCT成像装置适于获取受验对象的眼睛的视网膜的OCT图像的相干长度和波长的光束作为光束200。
In an optical system 100'-1 according to a first embodiment (or the variant thereof) described herein, the light source 20 may be configured to provide, as the light beam 200, a light beam having a coherence length and a wavelength that would render an OCT imaging apparatus comprising the optical system 100'-1 (or 100'-1*) suitable for acquiring OCT images of a retina of an eye of a subject.
光源20可以例如被配置成提供相干长度在1米和10米之间(例如在1米和2米之间)的光束200。
The light source 20 may, for example, be configured to provide a light beam 200 having a coherence length between 1 and 10 meters, for example, between 1 and 2 meters.
光源20还可以被配置成提供红外光谱的光束200，即，波长从800至1400nm的光束。
The light source 20 may further be configured to provide a light beam 200 of the infrared spectrum, i.e. a light beam having wavelengths from 800 to 1400 nm.
光学系统100’-1(或100’-1*)可以优选地包括两个但不多于两个的反射器210。
The optical system 100'-1 (or 100'-1*) may preferably comprise two, but not more than two, reflectors 210.
在根据本文描述的第一实施例的光学系统100’-1(或其变型)中，获得特定光行进距离所需的反射器数量相对于传统光学系统可以减少。
In the optical system 100'-1 according to a first embodiment (or the variant thereof) described herein, the number of reflectors required to obtain a particular light-travelling distance may be reduced relative to conventional optical systems.
下文描述的至少一种效果可以与光学系统100’-1(或100’-1*)相关联。
At least one of the effects described hereinafter may be associated with an optical system 100'-1 (or 100'-1*).
光学系统100’-1或100’-1*可以比传统的光学系统轻，使得它更容易运输。
The optical system 100'-1 or 100'-1* may be lighter than a conventional optical system, making it easier to easier to transport.
附加地或替代地，由于需要较少的反射器，相对于传统光学系统的安装空间，可以获得小的安装空间。
Additionally or alternatively, since fewer reflectors are required, a small installation space may be obtained relative to an installation space of a conventional optical system.
与传统光学系统相比，光学系统100’-1(或100’-1*)可能更不易受误差影响，因为可以实现更好的反射对准。
The optical system 100'-1 (or 100'-1*) may be less susceptible to errors, as a better reflection alignment could be achieved, as compared to conventional optical systems.
图3c示出了根据本文第一示例方面的第二实施例的光学系统100’-2。
An optical system 100'-2 according to a second embodiment of the first example aspect herein is illustrated in Fig. 3c.
第二示例实施例对应于第一实施例，但是不同之处在于光束200的反射部分从最后的反射器210b被引导至光输出设备240的方式。
The second example embodiment corresponds to the first embodiment but differs in the way in which the reflected portion of a light beam 200 is guided from the last reflector 210b to the light output device 240.
替代地或附加地，第二示例实施例与第一实施例的不同之处在于，光束200入射到第一反射器210a上的部分从光输入设备230被引导至第一反射器210a的方式。
Alternatively or additionally, the second example embodiment may differ from the first embodiment in the way in which the portion of the light beam 200 incident on the first reflector 210a is guided from the light input device 230 to the first reflector 210a.
根据第二示例实施例的光学系统100’-2在结构上类似于根据上述第一实施例的光学系统100’-1，但是附加地包括至少一个镜面元件270(换句话说，诸如反射镜的反射元件)。
The optical system 100'-2 according to the second example embodiment is structurally similar to the optical system 100'-1 according to the first embodiment described above, but additionally comprises at least one specular element 270 (in other words, a reflective element such as a mirror).
至少一个镜面元件270被配置成反射光束200，使得光束200被镜面元件270反射的部分和/或光束200入射到镜面元件270上的部分不平行于光束200入射到反射器210a和210b中任何一个上的部分。
The at least one specular element 270 is configured to reflect the light beam 200 such that the portion of the light beam 200 reflected by the specular element 270 and/or the portion of the light beam 200 incident on the specular element 270 are not parallel to the portions of the light beam 200 incident on any one of the reflectors 210a and 210b.
在光学系统100’-2中，光束200可以在从最后的反射器210b被最后反射之后被镜面元件270反射(见图3c)。
In the optical system 100'-2, the light beam 200 may be reflected by a specular element 270 after being last reflected from the last reflector 210b (see Fig. 3c ).
因此，可以防止光束200再次通过反射器210a和210b中的至少一个。
The light beam 200 may thus be prevented from passing at least one of the reflectors 210a and 210b any more times.
相反，光束200可以被转移到光学系统100’-2的外部。
Instead, the light beam 200 may be diverted to outside of the optical system 100'-2.
镜面元件270因此可以充当输出元件，以从光学系统100’-2提取光束200。
The specular element 270 may therefore act as an output element to extract the light beam 200 from the optical system 100'-2.
类似地，光束200可以首先入射到第一反射器210a的特定部分上，在没有镜面元件270的情况下，光束200很难或不能入射到该特定部分上。
Likewise, the light beam 200 may first be incident on a particular portion of a first reflector 210a, on which the light beam 200 could hardly or not be incident in absence of the specular element 270.
这是因为，在某些情形中，如果光束200要直接瞄准这样的特定部分，另一个反射器可能会挡路。
That is because, in some cases, another reflector may be in the way if a light beam 200 were to be directly aimed at such a particular portion.
例如，图3c的配置可以反向操作，其中镜面元件270作为输入元件将光束200引入光学系统100’-2，而不是作为输出元件。
For example, the configuration of Fig. 3c could be operated in reverse, with specular element 270 acting as an input element to introduce the light beam 200 to the optical system 100'-2, rather than as an output element.
注意，后一种情形没有在图3c中进行描绘，但是仍然形成了本公开的一部分。
It is noted that the latter case is not depicted in Fig. 3c, but nevertheless forms part of the present disclosure.
在图3c所描绘的示例实施例中，光束200由镜面元件270反射的部分垂直于光束200首先入射到第一反射器210a上的部分。
In the example embodiment depicted in Fig. 3c, the portion of the light beam 200 reflected by the specular element 270 is perpendicular to the portion of the light beam 200 first incident on the first reflector 210a.
然而，光束200由镜面元件270反射的部分和光束200首先入射到第一反射器210a上的部分可替代地形成0°和90°之间的任何角度，其中0°被排除并且90°被包括在内。
However, the portion of the light beam 200 reflected by the specular element 270 and the portion of the light beam 200 first incident on the first reflector 210a may alternatively form any angle between 0 and 90°, wherein 0° is excluded and 90° is included.
这种角度的示例可以是但不限于60°、45°、30°、20°、或10°。
Examples of such an angle may be, without limitation, 60° 45°, 30°, 20°, or 10°.
镜面元件270还可以被配置成使得其至少部分地反射入射在其一侧上的光束200，并且至少部分地允许入射在其另一侧上的光束200的透射。
The specular element 270 may further be configured such that it at least partially reflects a light beam 200 incident on one side thereof, and at least partially allows transmission of a light beam 200 incident on another side thereof.
镜面元件270还可以被配置成使得其仅一小部分(例如面积为1mm2的部分)反射入射光束200，而镜面元件270的其余部分允许光束200透射。
The specular element 270 may further be configured such that only a small portion thereof, e.g. a portion having an area of 1 mm2, reflects an incident light beam 200, whereas the rest of the specular element 270 allows transmission of a light beam 200.
还应注意，本文第一示例方面的第一示例实施例的框架中描述的限定和变型也可应用于如上所述的本文第一示例方面的第二示例实施例。
It is further noted that the definitions and variations described in the framework of the first example embodiment of the first example aspect herein may also be applied on the second example embodiment of the first example aspect herein as described above.
同样，可以获得相似或相等的技术效果。
Likewise, similar or equal technical effects may be obtained.
图3d示出了根据本文第一示例方面的第三示例实施例的光学系统100’-3。
An optical system 100'-3 according to a third example embodiment of the first example aspect herein is illustrated in Fig. 3d.
第三示例实施例对应于第一示例方面的第一示例实施例，但是不同之处在于光束200从最后的反射器最后反射的部分被引导至光输出设备240的方式。
The third example embodiment corresponds to the first example embodiment of the first example aspect but differs in the way in which the portion of the light beam 200 last reflected from the last reflector is guided to the light output device 240.
替代地或附加地，第三示例实施例与第一实施例的不同之处可以在于光束200被引导至第一反射器的方式。
Alternatively or additionally, the third example embodiment may differ from the first embodiment in the way in which the light beam 200 is guided to the first reflector.
在光学系统100’-3中，反射器210e和210f中的至少一个设置有至少一个反射表面280和至少一个光束通道260。
In the optical system 100'-3, at least one of the reflectors 210e and 210f is provided with at least one reflecting surface 280 and at least one light beam passage 260.
至少一个光束通道260位于至少一个反射器的至少一个反射表面280上。
The at least one light beam passage 260 is located on the at least one reflecting surface 280 of the at least one reflector.
此外，至少一个光束通道260被配置成允许光束200从其中透射穿过。
Further, the at least one light beam passage 260 is configured to allow transmission of the light beam 200 therethrough.
如图3d所描绘的，光束通道260可以由延伸穿过相应反射表面280并穿过整个反射器210e的开口形成。
As depicted in Fig. 3d, the light beam passage 260 may be formed by an opening extending through the respective reflecting surface 280 and through the entire reflector 210e.
光束通道260可以与反射中心轴250对准，或者可以包围反射中心轴250。
The light beam passage 260 may be aligned with, or may enclose, the reflection centre axis 250.
然而，替代地或附加地，在光学系统100’-3中，光束通道260可以通过局部改变反射表面280的一部分来形成，使得光束200入射到被改变部分上的部分透射穿过所述部分。
However, alternatively or additionally, in the optical system 100'-3, the light beam passage 260 may be formed by locally altering a portion of the reflecting surface 280 such that the portion of the light beam 200 incident on the altered portion is transmitted through said portion.
在图3d所描绘的实施例中，光束200被最后的反射器210f最后反射的部分透射穿过形成在反射器210e中的光束通道260。
In the embodiment depicted in Fig. 3d, the portion of the light beam 200 last reflected by the last reflector 210f is transmitted through the light beam passage 260, which is formed in the reflector 210e.
因此，可以防止光束200更多次通过反射器210e和210f中的至少一个。
The light beam 200 may thus be prevented from passing at least one of the reflectors 210e and 210f more times.
光束通道260充当输出元件，以从光学系统100’-3提取光束200。
The light beam passage 260 acts as an output element to extract the light beam 200 from the optical system 100'-3.
同样，在本文的另一个示例实施例中，光束200可以在透射穿过形成在另一个反射器210中的光束通道260之后首先入射到反射器上。
Likewise, in another example embodiment herein, the light beam 200 may first be incident on a reflector after having been transmitted through a light beam passage 260 formed in another reflector 210.
例如，图3d的配置可以反向操作，其中光束通道260作为输入元件将光束200引入光学系统100’-3，而不是输出元件。
For example, the configuration of Fig. 3d could be operated in reverse, with beam passage 260 acting as an input element to introduce the light beam 200 to the optical system 100'-3, rather than an output element.
注意，后一种情形没有在图3c中被描绘，但是仍然形成了本公开的一部分。
It is noted that the latter case is not depicted in Fig. 3c, but nevertheless forms part of the present disclosure.
在图5a、图5b、图5c和图5d中描绘了根据本文第一示例方面的第三实施例的光学系统100’-3中可以使用的光束通道260的示例。
Examples of light beam passages 260 that may be utilized in an optical system 100'-3 according to the third embodiment of the first example aspect herein are depicted in Figs. 5a, 5b, 5c and 5d.
举例来说，图5a和图5b描绘了均具有三个反射表面280a、280b和280c的隅角立方棱镜210-5和210-6形式的反射器。
By way of example, Figs. 5a and 5b depict reflectors in the form of corner cube prisms, 210-5 and 210-6, each having three reflective surfaces, 280a, 280b and 280c.
反射表面280a、280b和280c中的每一个都与另外两个反射表面正交。
Each of the reflective surfaces 280a, 280b and 280c is orthogonal to the other two reflective surfaces.
在图5a和图5b中，光束200入射到第一反射表面280a上并被第一反射表面280a反射，使得其入射到第二反射表面280b上。
In Figs. 5a and 5b, the light beam 200 is incident on a first reflective surface 280a and reflected by the first reflective surface 280a such that it is incident on a second reflective surface 280b.
随后，光束200被第二反射表面280b反射，使得其入射到第三反射表面280c上。
Subsequently, the light beam 200 is reflected by the second reflective surface 280b such that it is incident on a third reflective surface 280c.
光束200然后被第三反射表面280c反射，使得光束200最终被隅角立方棱镜反射的部分平行于光束200入射到第一反射表面280a上的部分。
The light beam 200 is then reflected by the third reflective surface 280c so that the portion of the light beam 200 finally reflected by the corner cube prism is parallel to the portion of the light beam 200 that is incident on the first reflective surface 280a.
第二光束200x也入射到隅角立方棱镜上。
A second light beam, 200x, is also incident on the corner cube prism.
然而，在图5a的示例中，第二光束200x入射到形成在反射表面280c上的光束通道260上。
However, in the example of Fig. 5a, the second light beam 200x is incident on a light beam passage 260 formed on the reflective surface 280c.
因此，第二光束200x透射穿过隅角立方棱镜210-5。
Thus, the second light beam 200x is transmitted through the corner cube prism 210-5.
在图5a的示例中，光束通道260是反射表面280c的被改变部分，其允许光束200x透射。
In the example of Fig. 5a, the light beam passage 260 is an altered portion of the reflective surface 280c that allows transmission of the light beam 200x.
图5b的示例对应于图5a的示例，尽管图5b所示的隅角立方棱镜210-6中的光束通道260-6是延伸穿过隅角立方棱镜210-6的物理开口，从而也在反射表面280c上提供了开口。
The example of Fig. 5b corresponds to the example of Fig. 5a, although the light beam passage 260-6 in the corner cube prism 210-6 illustrated in Fig. 5b is a physical opening that extends through the corner cube prism 210-6, thereby also providing an opening on the reflective surface 280c.
图5c和图5d中描绘的示例分别类似于图5a和图5b中描绘的示例。
The examples depicted in Figs. 5c and 5d are similar to the examples depicted in Figs. 5a and 5b, respectively.
然而，在图5c和图5d的示例中，使用均包括三个正交的反射镜211a、211b和211c的隅角立方镜210-7和210-8代替隅角立方棱镜。
However, in the examples of Figs. 5c and 5d, corner cubes 210-7 and 210-8 each comprising three orthogonal mirrors, 211a, 211b and 211c, are utilized instead of corner cube prisms.
注意，图5c和图5d的三个正交反射镜211a、211b和211c提供了相应的反射表面。
It is noted that the three orthogonal mirrors 211a, 211b and 211c of Figs. 5c and 5d provide respective reflective surfaces.
在图5a、图5b、图5c和图5d的示例中，第二光束200x可以是由于被另一个反射器210(如隅角立方棱镜(未示出))反射而再次进入所描绘的隅角立方棱镜(或者，在图5c和图5d的情形中，隅角立方镜)的第一光束200的反射。
In the examples of Figs. 5a, 5b, 5c, and 5d, the second light beam 200x may be a reflection of the first light beam 200 re-entering the depicted corner cube prism (or, in the case of Figs. 5c and 5d, corner cube) due to reflection by another reflector 210, such as a corner cube prism (not shown).
还应注意，本文第一示例方面的第一实施例的框架中描述的限定和变型也可应用于如上所述的本文第一示例方面的第三实施例。
It is further noted that the definitions and variations described in the framework of the first embodiment of the first example aspect herein may also be applied on the third embodiment of the first example aspect herein as described above.
在上述实施例中，基本上描述了在光束200首次入射到第一反射器210上之前可以如何处理光束200的三种方式。
In the embodiments described above, substantially three ways are described of how a light beam 200 may be treated before it is first incident on a first reflector 210.
同样，基本上描述了在光束200从最后的反射器被最后反射之后可以如何处理光束200的三种方式。
Likewise, substantially three ways are described of how a light beam 200 may be treated after it is last reflected from a last reflector.
然而，要注意的是，这些方式的每种组合可以被视为本文第一示例方面的另一实施例。
However, it is noted that each combination of the ways may be regarded as another embodiment of the first example aspect herein.
可选地，根据本文第一示例方面的另一实施例，如上所述的本文第一示例方面的相同或不同实施例的多个光学系统可以串联连接，以便进一步增加相应光束200的行进距离。
Optionally, according to another embodiment of the first example aspect herein, multiple optical systems of the same or of different embodiments of the first example aspect herein as described above may be serially connected in order to further increase the travelling distance of the respective light beam 200.
根据本文第二示例方面的实施例的用于光学相干断层扫描装置的光学延迟线可以包括根据上述第一示例方面的任何实施例的光学系统。
An optical delay line for an optical coherence tomography apparatus according to an embodiment of the second example aspect herein may comprise an optical system according to any of the embodiments of the first example aspect described above.
根据本文第三示例方面的实施例的光学相干断层扫描装置可以包括根据上述第一示例方面的实施例中的任何一个实施例的光学系统，或者根据上述第二示例方面的实施例的光学延迟线。
An optical coherence tomography apparatus according to an embodiment of a third example aspect herein may comprise an optical system according to any of the embodiments of the first example aspect described above, or the optical delay line according to the embodiment of the second example aspect as described above.
根据本文第三示例方面的实施例的光学相干断层扫描装置可以包括示例性OCT装置的元件，例如，本申请的上述以及图1和图2a至图2c中所示的那些。
