Abstract
A compact integrated optical system including an eyepiece, a reflective telescope, and a multi-spectral combiner optically coupled between the reflective telescope and the eyepiece, and configured to direct visible light received via the reflective telescope assembly along a direct view optical path to the eyepiece assembly. In one example, the multi-spectral combiner includes a display that displays a visual representation of the imagery of the viewed scene, and laser range-finder transceiver that transmits and receives a laser beam via the reflective telescope. A pair of beamsplitters is used to separate the imaging optical path from the direct view and laser range-finding optical paths. A blocking device is used to enable laser range-finding capability during daytime viewing of the imaging optical path imagery on the display. The reflective telescope provides a common aperture for the direct view optical path, an imaging optical path, and the laser range-finder transceiver.
