Abstract:
A compact fully integrated multifunctional multispectral sight assembly comprising:a single window;a single reflective afocal foreoptics unit for receiving and transmitting signals;a reflective optical field-of-view switch structure controllably movable between a first-field-of-view position that receives and transmits signals through the single reflective afocal foreoptics unit, and a second-field-of-view position that bypasses the single reflective afocal foreoptics unit to receive and transmit signals, both a first field of view and a second field of view being through the single window;at least two subsystems in controllable optical communication with said reflective optical switch, at least one of the subsystems operating in a visible wavelength range and including an eyepiece, and at least one of the subsystems operating in an infrared wavelength range.
