DETAILED DESCRIPTION OF THE INVENTION
While the making and using of various embodiments of the present invention are discussed in detail below, it should be appreciated that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention and do not delimit the scope of the invention. For example, the embodiments described below relate to an imaging device for a gun scope, but are applicable to any type of sighting, spotting or targeting scope.
The imaging device allows one or more images, which someone views thru a gun, sighting, spotting and targeting scope, to be unobtrusively recorded or viewed by another person. Moreover, the imaging device is lightweight and does not materially alter the weight distribution of a gun or the mounting of a scope on the gun. The imaging device can be used for hunting, bird watching, surveillance, training, governmental and military applications, etc.
Now referring to FIG. 1, a cross-sectional view of an imaging device 100 mounted on a scope 102 in accordance with one embodiment of the present invention is shown. The imaging device 100 has a housing 104, an optoelectronic detector 106, a beam splitter 108, a field lens 110, a mirror 112, a control circuit 114, a memory 116, a user interface 118 and a power source 120. The housing 104 is configured to be mounted in an optical path 122 (i.e., line of sight) of the scope 102. The housing 104 can be made of plastic, rubber or other suitable materials. The optoelectronic detector 106 (e.g., camera, etc.) is mounted within the housing 104 outside of the optical path 122 of the scope 102. The beam splitter 108 is mounted within the housing 104 in line with the optical path 122 of the scope 102. The field lens 110 (e.g., a plano convex (PCX) lens, etc.) is mounted within the housing 104 in line with a reflected optical path 124 of the beam splitter 108. The mirror 112 is mounted within the housing 104 such that the reflected optical path 124 of the beam splitter 108 from the field lens 110 is reflected to the optoelectronic detector 106.
The control circuit 114 is disposed within the housing 104 and connected to the optoelectronic detector 106. Note that the control circuit 114 may perform various image processing functions, such as enhancing or filtering the image captured by the optoelectronic detector 106. Moreover, the control circuit 114 may automatically turn the imaging device 100 off based on a timer, an absence of light detected by the optoelectronic detector 106, or a combination thereof. The memory 116 (e.g., flash memory, a secure digital (SD) card, etc.), which can be removable, is disposed within the housing 104 and connected to the control circuit 114. The user interface 118 (e.g., buttons, etc.) is disposed on the housing 104 and connected to the control circuit 114. The user interface 118 may include various buttons or controls, such as an on/off switch, one or more image adjustment controls, one or more light adjustment controls, one or more data connectors, or a combination thereof. The power source 120 (e.g., battery, etc.) is disposed on or within the housing 104 and connected to the control circuit 114. The power source 120 can be a battery, a solar cell, a power connector, or a combination thereof.
The optical path 122 projects the subject to the eye of the person looking through the scope 102. The beam splitter 108 transmits the image light to both the pupil of the person looking through the scope 102 and the optoelectronic detector 106. The field lens 110 increases the size of the image and decreases the eye relief to allow the optoelectronic detector 106 to be positioned closer to the mirror 112, which reduces the size of the imaging device 100. The optoelectronic detector 106 records the image presented by the beam splitter 108 to the memory 116 for later retrieval. The imaging device 100 may include a data/power connector 126 (e.g., a universal serial bus (USB), etc.) connected to the control circuit 114 that allows a user to access the control circuit 114 to configure various settings, the memory 116 to retrieve stored or real-time images, or recharge the power source 120. The imaging device 100 may also include a wireless transceiver disposed on or within the housing 104 and connected to the control circuit 114 that allows data to be sent to and received from a remote device.
The housing 104 includes a recessed portion 128 aligned with the optical path 122 of the scope 102 that frictionally engages the scope 102 such that tools are not required. The optoelectronic detector 106, the control circuit 114, the memory 116, the user interface 118 and the power source 120 are disposed above or partially disposed above the recessed portion 128. The housing 104 may also be secured to the scope 102 using one or more fasteners attached to the housing 104 that engage the scope 102.
