Abstract

The invention discloses a background-radiation-controllable infrared point source target simulator. The background-radiation-controllable infrared point source target simulator comprises an optical projection system, a beam combiner, an infrared point target component, a liquid nitrogen circulating system, a background lighting optical system and an infrared background component and is characterized in that an infrared point target source formed by the infrared target component forms an infinite-distance infrared point target through the beam combiner and the optical projection system; an infrared point source formed by the infrared background component is amplified by the background lighting optical system, reflected by the beam combined and projected by the optical projection system to form an infrared background filling the whole view field; the liquid nitrogen circulating system performs cooling when the infrared point target component forms the infrared point target source and theinfrared background component forms the infrared point source. The background-radiation-controllable infrared point source target simulator has the advantages the background-radiation-controllable infrared point target source is provided, and the problem that the background radiation of a traditional infrared point source target simulator cannot be controlled in a quantified manner is solved.

Description

technical field [0001] The invention relates to the technical field of infrared point source target simulation. More specifically, it relates to an infrared point source target simulator with controllable background radiation. Background technique [0002] Generally, the point source infrared target simulator does not control the background radiation. When there are some tests that require a specific radiation level background to detect infrared targets, not only the infrared point source target, but also the infrared background of the corresponding radiation intensity need to be given. , conventional infrared target simulators are not up to the task. [0003] Therefore, it is necessary to provide an infrared point source target simulator with controllable background radiation. Contents of the invention [0004] The object of the present invention is to provide an infrared point source target simulator with controllable background radiation, which solves the problem that...
