Versatile Deflectometry Applications

Various applications in deflectometry optical testing are presented in this paper. The final accuracy of optics systems is determined by the accuracy of the metrology. While commercially available and standardized testing approaches exist, they may be challenging to adopt in different application environments due to strict optical layouts and limited dynamic range. In response, our group has been developing versatile deflectometry systems capable of addressing diverse optical testing demands. The paper summarizes various deflectometry types tailored to unique missions.
