Description

Technical Field

[0001] The present invention relates to the technical field of optical testing, and particularly to a portable composite target simulator for laser, visible light, and infrared light. Background Art

[0002] A target simulator is an important component of a semi-physical simulation system for a guided vehicle. It supplies a stable optical target for the optoelectronic system to be tested and plays an important role in the research and development and testing processes. There are usually single optical target simulators for laser, visible light, and infrared light, with limited usage scenarios. At the same time, some composite optical target simulators are large in volume and weight and have low portability; moreover, the optical axis consistency of conventional composite target simulators is lacking and the simulation effect is not good; the conventional infrared radiation source is an infrared target simulator with a black body, and the radiation surface has an absorption capacity for the visible and near-infrared bands, and the radiation surface is relatively large, which affects the output energy of the composite light source in the laser and visible bands, and the accuracy of the test effect is low. Summary of the Invention
