基于改进的马赫-曾德干涉仪设计，研制了波前传感器对比分析光学试验台。该系统通过使用一个共像差来同时测量同一相机上的波前传感器。该试验台的最初应用是评估参考马赫-曾德干涉仪的Shack-Hartmann和相分集波前传感器。在测试平台的当前配置中，使用液晶空间光调制器控制像差，并使用可变形镜进行校正。该试验台还可以训练变形镜对抗空间光调制器，并评估其对空间光调制器的补偿能力。本文给出了光学试验台波前传感器的测试结果。
An optical testbed has been developed for the comparative analysis of wavefront sensors based on a modified Mach Zender interferometer design. This system provides simultaneous measurements of the wavefront sensors on the same camera by using a common aberrator. The initial application for this testbed was to evaluate a Shack-Hartmann and Phase Diversity wavefront sensors referenced to a Mach-Zender interferometer. In the current configuration of the testbed, aberrations are controlled using a liquid crystal spatial light modulator, and corrected using a deformable mirror. This testbed has the added benefit of being able to train the deformable mirror against the spatial light modulator and evaluate its ability to compensate the spatial light modulator. In the paper we present results from the wavefront sensors in the optical testbed.
