摘要
结合液晶空间光调制器(LC-SLM)的可编程相位调制能力,分析了基于LC-SLM 的相位型光栅波前曲率传感器的实现方法。在此基础上,研究了基于拉普拉斯算子本征函数的闭环波前复原方法,通过数值仿真分析了该方法的精度和稳定性。结果表明,与开环复原方法相比,闭环复原方法具有更高的精度和更大的测量范围,而且模式耦合对其稳定性影响很小。
Abstract
Considering the programmable phase modulation ability of liquid crystal spatial light modulator (LCSLM), the implementation of phase grating wavefront curvature sensor based on LC-SLM is introduced. A closeloop phase retrieval method based on eigenfunctions of Laplacian is proposed, and its accuracy and effective range and stability are analyzed through numerical simulation. The simulation results show that comparing with the open-loop phase retrieval method the close-loop phase retrieval method has a higher accuracy and a larger effective range. Moreover, the close-loop phase retrieval method is stable regardless of modal cross coupling.
