Infrared and night vision optical fusion systems are provided. The first scheme is to add a common-aperture beam splitter in front of the night vision device, which is a band-pass filter having a high transmission for the light with wavelength of 0.78-1 m, and a high reflectivity for the visible light with wavelength of 0.38-0.78 m and for the infrared light with wavelength of 8-14 m. After electrical processing, a target image with a temperature higher or lower than a certain threshold is obtained on the LCD/OLED. The second scheme is to align the night vision objective lens and the infrared objective lens having the same field of view side by side. Since only infrared targets having a temperature above or below a certain threshold are used, white or red humans, animals and vehicles can be clearly seen in a green night vision background with high contrast no matter which scheme is adopted.

A targeting receiver operates with beam emitters. Each emitter generates coherent beams directed towards a target as a composite beam having an associated signature. For each composite beam, the target reflects a proportion of radiation intensity as a reflected radiation component. A receiver telescope collects target-reflected radiation and directs the radiation to a spatial filter. The reflected radiation includes radiation components, at least some of which are combined as a combined radiation composed of the reflected radiation components. Intensity of the combined radiation indicates the intensity of the composite beams impinging on the target. The spatial filter filters the reflected radiation by selectively passing the combined radiation. Each component of the combined radiation is identifiable by the signature associated with the composite beam corresponding to the component of the combined radiation. In certain embodiments, a distinguishing module is associated with the receiver and distinguishes the components based on the signature.

An unobscured five-mirror afocal telescope includes an aperture configured to direct electromagnetic radiation to first, second, third, fourth and fifth mirrors, each configured to receive electromagnetic radiation and reflect electromagnetic radiation along a beam path. The five mirrors are arranged to sequentially reflect from one another electromagnetic radiation received via the aperture to produce a collimated output beam of the electromagnetic radiation at an exit pupil, with the five mirrors consisting of a three-element objective and a two-element eyepiece. A beam splitter may be disposed between the first mirror and the second mirror to direct short-wavelength electromagnetic radiation toward a device along a separate path.
