Abstract:

An outdoor scene simulating apparatus for testing an infrared imaging device comprising an infrared source, which emits infrared energy along a first optical path. Positioned downstream from the infrared source along the first optical path is a metallic substrate which has on its front surface a simulated outdoor scene. The simulated outdoor scene is formed by coating a portion of the metallic substrate with a black ink which absorbs infrared radiation. A thermal mass abuts the substrate to provide a cooling path between the thermal mass and the substrate. The thermal mass cools the metallic substrate and black ink of the simulated outdoor scene to temperatures below ambient temperature reducing infrared emissions from the metallic substrate and black ink of the simulated outdoor scene. Infrared energy reflected from the metallic substrate is directed along a second optical pam to a collimator. The collimator collects the infrared radiation reflected from on metallic substrate and then redirects the infrared radiation as a collimated beam of infrared radiation along a third optical path to the lens of the infrared imager being tested.
