Rapid detection method and system for tilting mirrors in ultra-high contrast imaging instruments

Abstract

This invention discloses a rapid detection method and system for a tilting mirror in an ultra-high contrast imaging instrument. The detection system includes a laser source, optical fiber, collimating lens, tilting mirror under test, imaging mirror, high-speed detector, image acquisition card, signal generator, and tilting mirror controller. This invention enables rapid and automated detection of the stabilization performance of the tilting mirror at different operating frequencies, and screens and records the actual resonant frequency of the tilting mirror under load conditions. This frequency can be avoided during mirror operation, ensuring normal image stabilization. Specifically designed and optimized for the detection needs of tilting mirrors in ultra-high contrast imaging instruments, it not only calibrates the tilting mirror's own response but also detects its image stabilization correction capability. Automatic calibration and image stabilization monitoring of the tilting mirror can be achieved through LabVIEW electronic control programs, reducing human interference. The compact optical path structure facilitates integration with pre-disturbance optical paths configured for different research needs, offering flexible and convenient application.
