Composite visible/thermal-infrared imaging apparatus
First Claim
1. Multispectral imaging apparatus comprising a wavelength independent focus reflecting optical system for receiving visible and infrared radiation from a scene and for focusing the visible and infrared radiation at respective first and second focal planes which are located the same distance from the optical system;
- first detector means disposed at the first focal plane for receiving the visible radiation and for providing a first signal corresponding thereto;
second detector means disposed at the second focal plane for receiving the infrared radiation and for providing a second signal corresponding thereto; and
means responsive to the first and second signals for displaying a composite image of the scene, the composite image comprising a black and white visible image of the scene with portions of the image highlighted in color in accordance with the infrared radiation received from corresponding portions of the scene.

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.
