介绍了一种基于液晶空间光调制器的新型移相像素化干涉仪，并模拟了预期的性能。相移帧被同时捕获，这减少了由振动和空气湍流引起的问题。液晶空间光调制器是灵活的，并且可以被配置为提供大量的相移水平和几何形状以减少测量误差。
We introduce a novel phase-shifting pixellated interferometer based on a liquid-crystal spatial light modulator and simulate the expected performance. The phase-shifted frames are captured simultaneously, which reduces problems arising from vibrations and air turbulence. The liquid-crystal spatial light modulator is flexible and can be configured to provide a large number of phase-shift levels and geometries to reduce measurement error.
