Abstract:
1. A system to provide feedback about a position of a reticule that is moveable within a telescope that provides a visual image to a viewer, the system comprising: a light source configured to generate an illuminating light; a camera configured to produce a captured image in response to received light; optics configured to direct the illuminating light from the light source and through the telescope to the eye of the viewer so that the illuminating light reflects off the eye of the viewer toward the reticle and thereby illuminates the reticule with reflected illuminating light to thereby form an illuminated image of the reticle in an outgoing direction of the telescope, wherein the optics are further configured to transmit the illuminated image of the reticle in the outgoing direction to be received by the camera to thereby allow the camera to create the captured image representing the illuminated image of the reticle that is moveable within the telescope; and processing electronics configured to receive the captured image from the camera that is based upon the illuminating light and to determine the position of the reticle as the reticle moves within the telescope based upon a position of the illuminated image of the reticle within the captured image.
