| 摘 要： | 针对不同非球面面形的实时检测需求,研究了基于空间光调制器的标准波面重建技术.基于空间光调制器波面重建的原理设计了干涉测量系统,依据空间光调制器的自身特点选取修正离轴计算全息编码方式实现对标准球波面的编码.针对实验中空间光调制器作为全息再现介质引起重建波面质量下降问题,提出了错位叠加优化方案,并将这一过程进行了模拟实验....

| Abstract: | A wavefront reconstruction method was proposed based on spatial light modulator(SLM) to achieve the requirement of real-time testing of different aspheric surfaces.An interference measurement system based on SLM wavefront reconstruction was designed,in which the computer-generated hologram(CGH) encoding method was chosen according to the intrinsic properties of SLM.To resolve the quality degradation problem of the reconstructed wavefront,a dislocation optimization method was proposed.The process is verified... |
