Opto-mechanical Structure Design Of The Testing System For Laser Irradiating Stability

With the development of modern weaponry,the guidance accuracy of laser tracking and guidance system is also improving.Especially for moving targets,the stability of laser irradiation determines the hit precision of laser guided weapons.How to make rapid,accurate and effective detection is particularly important.In this paper,an instrument for detecting the relative position offset of a laser guidance system and a moving target is designed.The system is mainly composed of visible light observation system,infrared observation system,visible light tracking system,laser echo system.The visible light observation system and the infrared observation system adopt a dual-band shared-aperture structure.By sharing a Cassegrain system,effectively increasing the system aperture and focal length,and the overall weight and volume of the system are reduced.According to the design results of the optical system,the mechanical structure design scheme of laser irradiation stability detection system is proposed,and focuses on the integrated analysis of the system.Finally,through the high and low temperature experiment,the rationality of system structural design and the accuracy of optical-mechanical integration analysis are verified.
