Research on Optical Testing Method for Laser Damage Effectiveness Evaluation in High-Speed Wind Tunnel

Under the technical background of testing requirements for laser damage effectiveness evaluation, this project has formed a set of relatively comprehensive optical testing method for evaluating laser damage effectiveness in high-speed wind tunnel from the aspects of optical testing system composition, test layout design, system debugging, parameters setting, data processing, etc., which can comprehensively and effectively meet the testing requirements and complete relevant testing tasks. Starting from preliminary investigation and demonstration, this research delves into the mechanism of laser damage and the macroscopic characteristics of the target, determines the technical route of adopting high-speed photography method, and summarizes the setting rules of photography parameters for different experimental combinations. The research content enriches the technical means and application fields of the current optical testing profession, and accumulates technical experience for undertaking the same type of laser damage verification testing tasks in the future.
