Laser Infrared Visible Light Three-mode Composite Target Simulator

Abstract

The invention discloses a novel laser, infrared light and visible light three-mode combined target simulator. The simulator comprises a three-mode light source simulation system (1), a scanning reflector system (2), a tested system (9), a three-axis attitude simulation rotary table (10), a measurement and control system, a supporting platform (11) and an adapter tool, wherein the three-mode lightsource simulation system (1) and the scanning reflector system (2) are installed on the supporting platform (11), and the tested system (9) is installed and fixed on an inner rolling ring of the three-axis attitude simulation rotary table (10). Through the simulator, an infrared light, visible light and laser three-mode light source dodging and attenuation method can be implemented, and lasers aredivided into interference light, a coding simulation light source and a ranging simulation light source; and through the method, simulation of multiple light sources can be realized, multiple simulation test demands such as laser imaging and four-quadrant and unit detection can be met, and the interference light can meet the anti-interference test demand.

Description

technical field [0001] The invention relates to the technical field of multi-mode optical compounding, and relates to a laser infrared visible light three-mode compound target simulator. Background technique [0002] The multi-mode composite imaging system is one of the important development directions of photoelectric imaging technology in the future. It can make up for the shortcomings and disadvantages brought by a single imaging sensor, and can obtain more abundant, objective and comprehensive information of the target. The target in remote sensing optical imaging It plays an important role in detection, identification and tracking. [0003] Multi-mode composite imaging technology began in the 1970s. The United States first developed an infrared / ultraviolet dual-mode composite imaging system, which is the earliest optical multi-mode imaging sensor. By using the multi-mode optical compound imaging system, the anti-interference ability, identification ability and tracking...
