Description: APPARATUS FOR THE RELATIVE INCREASE OF DEPTH SHAR P ¬ NE SS AND IMPROVEMENT OF RESOLVING POWER OF MAGNIFYING SYSTEMS , PARTICULARLY MICROSCOPE S Technical field The inventio relates to an apparatus for the relative increase of depth sharpness and improvement of re solving power of magnifying systems , particularly micro scope s . Background art In technical practice but also in other, so e . g. medical, biologica fields increase of depth sharpness and improvement of resolving power of magnifying systems , in particular microscopes represent still a task to be solved. For the adjustment of the image plane or in case of imaging in a ratio of 1: 1 at most mat glass-sheets used to be applied. In these cases mat glass-sheets are fixed, as an eventual displacement thereof does not result in a considerable improvement of image quality. It has been found in course of our experiments that if small objects are imaged with a considerable magnifying, i. e . in case of microscopic systems such an effect already appears. With this type of magnifying - among others - smallness of depth sharpness represents the limit of detect ing. We ascertained that by using the mat glass-sheets and moving them in the image plane an image with a better depth of sharpness ani richer in details could be obtained, that means that both depth sharpness and grade of magnifying could be increased in this manner and as a consequenc - 2 - applicability of the presently used microscopes can be increased. Disclosure of Invention The aim of the invention is that the image having been produced by the objective of an optical or physical composite magnifying system should be • : richer in details and the largest depth sharpness could be achieved. It has been a well known process to use mat glass-sheets for adjusting the image plane, mainly in case of reduced imaging, or at the best with imaging with a ratio of 1: 1. In this case displacement of the mat glass - - sheet does not result in a considerable improvement of image quality. The basic idea of the invention is based on the recognition that if small objects are imaged with a considerable magnifying; i. e. in case of microscopic systems the aforementioned displacement results in a special effect. In. this case detection is restricted - among others - by the small depth sharpness. According to our recognition by moving the mat glass- -sheet in the image plane both depth sharpness and grade of magnifying can be increased and applicability of the microscopes used up to now can. also be increased. The image thus obtained is far richer in details , in addition significant depth sharpness can be achieved. In accordance with the invention the task set has been achieved by insertion, into the image plane of the primary magnifier an image forming layer between the primary and secondary magnifier of the composite magnifying system, after the object £α respect to the travel of the beam which is formed by independent particles distributed in a medium having a different index of refraction, beside said image forming layer can be moved in. the image plane . Both the primary and the secondary magnifier can be a simple or composite magnifier, i. e. it may contain an objective and an ocul /or projector/ . In other words, the primary magnifier may consist of a primary objective and primary ocular /or projector/, while the secondary magnifier may comprise a secondary objective and a secondary ocular /or projector/. Movement of the image forming layer can. take place along any regular or irregular path. Moving along a circular path seems to be the most expedient. In the most simple case image forming layer can be a mat glass- - sheet, however , solid particles having been dispersed in a liquid - i. e . suspensions -, or liquid particles dispersed in a liquid - i. e . em ulsions or gas bubbles dispersed in a liquid - i. e . foams -, or liquid drops havi been dispersed in a gas - i. e . aerosols , that means disperse system s , furtheron colloid solutions can be successfully used as image forming lay Furtheron, mat surface of transparent solid materials can also be used, having a different index of refraction than that of the medium in which it is placed /theoretically vacuum is also a "medium with a different index of refraction" /. As an image forming layer: the mat surface of an opaque » material, where primary and secondary optical systems are arranged on the same side of the image forming layer, on the side corresponding to th mat surface , fiber optics, gas bubble dispersed in a transparent solid ma terial, solid grains , liquid drop or solid particles dispersed in a gas, e . smoke can also be taken into account. These image forming layers are in movement, while this moving can take place - as already mentioned before - on any regular or irregula path. However, beside said movements taking place on regular or irregul paths or even simultaneously therewith, other ovings are also possible , so e . g. a. rotary motion around its own axis of rotation, an alternating motion with irregularly changing velocity along a straight running parallel with the optical axis /axes/ of the apparatus enclosing an angle therewith, respectively. Within the image forming layer the particles dispersed in the medium having an index of refraction different from that of the particle s do not move or only to an inconsiderable extent in respect to the medium with the different index of refraction in certain cases , while in other case a considerable material flow can be observed within the image forming layer, besides , in the image forming layers the particles dispersed in the medium having an index of refraction different from that of the particle are even capable to luminescence. The independent particles taking part in buuding-up the image forming layer are able to produce luminescence, if their index of refraction does not differ from that of the medium in which they are dispersed. In case if the apparatus according to the invention for producing the image of the object practically any illuminating system can be used, in which the wavelength is different from the wavelength of the visible light, or emitting an electromagnetic radiation with a wavelength corresponding to the wavelength of the visible light or even an illuminating system emitting electron radiation. Tne application of any illuminating system of optional number, arrangement and actuated in any optional combination is permitted for illuminating the object at an optional angle, the more , these can be operat¬ ed in an optional combination and simultaneously. A preferred embodiment of ' the invention is provided with a strobo- scopic illuminating system. In the apparatus according to the invention possibilities of illuminating the object to be tested can be varied within wide limits: so e. g. illuminating can take place through a layer consisting of particles dispersed in a medium having an index of refraction different from that of any image forming layer, while this layer is arranged in the travel of the beam in the tract between the condenser and the object and the layer may move on a regular or irregular path. In case of using an image forming layer made of an opaque material illuminating is realized by means of the beam reflected from the mat surf ce ; in this case the mat surface - which is either stationary or moving - is arranged in the travel of the beam between tne condenser and the object, while the illuminating system is arranged on the same side , as the mat surface of the object. With another preferred embodiment of the invention illuminating is realized - by using any of the aforementioned image forming layers - through the layer consisting of particles having been dispersed in a medium with different index of refraction, while the layer is to be found in the path of the beam, in the tract between the source of light and radiation, respectively, and the condenser, and the layer can be stationary or moving. In case if a mat glass-sheet is used as an image forming layer, illuminating is realized through said mat glass- sheet and in this case the mat glass-sheet is arranged in the travel of the beam, between the source of light and radiation, respectively, and the condenser and moves there on a regular or irregular, e xpediently on a regular circular path, and simultaneously with said motion it may perform a rotary motion around its own axis of rotation with an optional velocity. With another preferred embodiment of the invention illuminating » is realized with a beam having been reflected from the mat surface of an image forming layer of opaque material, wherein the mat surface is lying in the travel of beam of the apparatus, in the section between the source of light and radiation, respectively, and the condenser and it is either stationary or it moves. With the preferred embodiments of the invention the bundle of rays is arranged in a closed casing surrounding the bundle of rays partially or totally. Into the travel of the beam of the apparatus - according to the invention - in any section thereof, any optical elements in any optional number, combination or geometric arrangement can be inserted, so a mirror, lens, prism, plane-parallel plate , fibre optics , filter , polarization, phase and interference contrast means , etc. With a further preferred embodiment in any optional section of the travel of the beam of the apparatus stroboscopes are arranged in any optional number and arrangement. With an expedient embodiment of the apparatus according to the invention in the visual field of the optical system, for producing the spatial image of the object the optical system has two primary magnifiers producing an image of the object each on the image forming surface at different angles , furtheron two secondary magnifiers , each projecting said images isolated into the two eyes of the viewer. With a still further preferred embodiment of the apparatus accor¬ ding to the invention the built-in objectives - primary, secondary, etc. - are performing an optional alternating movement, each separately, un- indirectionally with the optical axis and also in compliance therewith, with regular or irregular acceleration and velocity, respectively. According to a further preferred embodiment of the invention in the travel of the beam, along the optical axis more than two magnifiers and image forming layers are arranged, wherein the image having been produced by the secondary magnifier is projected to a further image forming layer and enlarged by a third - a tertiary - magnifier, that is said process is repeated on further image forming layers and when using a plurality of image forming layers and if at least one image forming layer is put into motion, the other image forming layers are either stationary or moving, in an optional combination. With all the preferred embodiments of the apparatus accordin to the invention every single optical and mechanical structural element taking part in building-up the apparatus are arranged sθ j as to enabling a movement in relation to each other along any optional regular or irregular path with any optional velocity and optional combination, while the object tested is arranged so that it could be moved along an optional regular or irregular path with an optional velocity. In any section of the path . of the beam of the preferred embodiments of the apparatus according to the invention a photo -camera, video-camera or any other layer sensitive to radiation, transducer is arranged, the said apparatuses are displacable along any optional path. In accordance with a further preferred embodiment of the invention the image forming layer is formed by the mat surface of two transparent solid materials , in this case mat surfaces of the two transparent solid materials are arranged on one another and facing each other, they are stationary or move in relation to each other on any regular or irregular path and between the two surfaces - not preventing the motion of the image forming layer - a material is to be found with an index of refraction being different from that of the particles of the mat surface , this material can be either a liquid, a gas , vacuum, or any solid or other type of ma ¬ terial. As already mentioned before , a variety of image forming layers can be used, however, for the sake of simplicity, furtheron we refer to a mat glass -sheet only. Granular surface of the mat glass -sheet is moving in the image - plane of the first - primary - magnifying stage of the composite magnifying system, while the beam coming from the object are projected by a simple or composite magnifier - furtheron primary magnifier - onto the granular surface of the mat glass-sheet, thus producing the image in the plane of the particles , i. e . the plane of the image of the primary magnifier coincides with the granular surface of the mat glass-sheet. This image is enlarged by another simple or composite magnifier - furtheron: secondary magnifier - that means, that the object -plane of the secondary magnifier coincides with .the granular layer of the mat glass -sheet. As already mentioned before , in course of image forming the mat glass-sheet is moving along some regular or irregular path . Up to now no example has been knownfor allowing t o move the mat glass -sheet in the image plane for obtaining an image richer in details and increasing depth sharpness. Brief De scription of the Drawing The invention will now be described by means of a preferred embodiment serving as example , by the aid of the accompanying drawing showing the side view of the schematical arrangement of the apparatus according to the invention. Be st Mode of Carrying out the Invention As it is to be seen in the figure , the illuminating system consists of a lamp 1, a collecting lens la and a mirror 2. In the path of the beam projected by the mirror 2 - in the figure vertically upwards - /in the so- called optical axis/ elements are arranged one above another: a condenser 3, an object 4 /generally a microscopic section/, a primary magnifier 5, a rotatable mat glass-sheet 6, a secondary objective 7 and a secondary ocular 8. The mat glass- sheet 6 can be rotated around the axis of rotation 6a, said axis of rotation 6a is arranged excentrically in relation to the optical axis. In the point of intersection of the mat glass- sheet 6 and the optical axis the image 6b of the object 4 is to be found. The bundle of rays having been projected by the illuminating system, by the aid of a condenser 3 through the object 4 is imaged by the primary magnifier onto the upper blind surface of the mat glass- sheet 6. The image 6b thus obtained is enlarged by the composite magnifier consistin of the secondary objective 7 and the secondary ocular 8. The microscopic photo -apparatus can be inserted onto the place of the secondary ocular 8. The advantages of the invention can be summarized, as follows: The composite microscope system, into which a mat glass-sheet was built-in, as described previously, in accordance with the invention is formed - as a matter of fact - by two microscopes placed one behind the other. The object points lying within the depth sharpness of the primary objective of the first microscope are imaged in one plane on the surface of the mat glass-sheet, while the image thus obtained is enlarged by the secondary magnifier. As a consequence, the image having been produced by the secondary magnifier keeps the depth sharpne ss of the primary magnifier. As a consequence of the movement of the mat glass - sheet the quality of the image appearing on the surface thereof will be improved, accordingly it can be further enlarged by the secondary mag¬ nifier. Thus in the whole system proportion of magnifying and depth sharpness will be shifted so that a given magnifying is accompanied by a larger depth sharpness, that means that depth sharpn ss of the optical system relatively increases. In such a manner it becomes possible to detec microscopic configurations lying in depper and thicker layers, than up to now, simultaneously possibility of examination of microscopic objects - 9 - will also be enlarged. At the same time resolving power of the magnify¬ ing system will also be improved. In accordance with the invention an apparatus can also be provided suitable to create the spatial image of an object. In this case simultaneously two optical systems are applied on the surface of the image forming layer by means of two primary magnifier two images are produced, each at a different angle , thereafter, viewing these images with a secondary magnifier each, the image produced by the secondary magnifier is project¬ ed isolated into the two eyes of the viewer. It goes without saying that the invention is not restricted to the embodiment described above by way of example only different other embodi¬ ments are also possible without leaving the scope of protection. So e . g. for producing the image of the object any other electromagnetic radiation with a wavelength different from the wavelength of visible light can be applied. Primary and secondary magnifiers can be arranged on the same or opposite sides of the plane of the image forming layer. In the first case the travel of beam is incident in respect to the image forming layer while transmitted in the second case . In case of incident beam travel mat surface of opaque materials can also form an image forming layer . Theoretically, it is possible to arrange more than two magnifiers as well as image forming layers in the travel of beam along the optical axis . In such a case the image having been produced by the secondary magnifier is pr ojecte d onto a further image forming layer, which again is furtuer enlarged by a third - tertiary - magnifier. Based on this principle several magnifying stages can be realized.
