ABSTRACT:
Multispectral imaging apparatus for producing a composite dual wavelength visible/infrared image includes a wavelength independent focus reflective optical system for receiving a visible and infrared radiation from a scene and for providing a focused beam of radiation, a beam splitter for splitting the beam into a beam of visible radiation and a beam of infrared radiation, a visible radiation detector for receiving the visible radiation and for producing a first signal, and infrared radiation detector for receiving the infrared radiation and for producing a second signal, and a signal processing and display system for converting the first and second signals into video signals corresponding to a visible black and white image of the scene and a step-tone or false color infrared image of the scene. The images are combined in exact spatial registration to produce a composite image comprising a black and white visible image with portions of the image highlighted in color in accordance with the infrared radiation received from corresponding portions of the scene.
