Problems solved by technology

[0003] And many photoelectric sensors, such as the MX series photoelectric turrets of the American L-3 company, the Longzhiyan series pods of AVIC Optoelectronics, etc., the products include multiple detection spectrum bands such as visible light, near-infrared, and mid-wave infrared. Larger, which adds great difficulty to the optical axis calibration of each sensor
The current optical axis calibration method often only meets the dual-band optical axis calibration function, and the calibration device is often bulky, which is not convenient for installation and testing with the product

Abstract

The invention discloses a multispectral automatic calibration system, and belongs to the technical field of multi-photoelectric sensor system testing. The system comprises an off-axis parabolic mirror, a reflector, a CCD image sensor, a composite light source, a laser energy receiver, a simulated laser echo, a cube-corner prism, a small spectroscope, a large spectroscope and an optical window. The off-axis parabolic mirror and the reflector form a test system light tube, the CCD image sensor and the composite light source are both located at the focus of the calibration optical light tube and are vertically conjugated relative to the small spectroscope, the composite light source is the test reference of the test system, and the CCD image sensor is used for self-inspection of the test system reference; the system has the advantages of being high in precision, compact in structure, light in weight and the like, comprehensive performance testing of multiple photoelectric load sensors can be achieved, and the system can be widely applied to the military and civil fields as a comprehensive performance testing platform of photoelectric loads such as a photoelectric pod, a photoelectric radar and a photoelectric brick tower.
