摘要
针对基于强光元件高精度面形在位检测需求,开展了面形测量误差敏感因素仿真分析,进行了系统结构误差和温度误差对测量结果的影响研究,分析各类误差对测量面形误差的具体影响,设计并搭建在位检测系统,开展系统温度变化、系统重复性、系统稳定性等测量实验。研究结果表明:所建立的逆向哈特曼仿真检测模型可用于平面、球面、非球面、自由曲面等各类型被测面,各类影响因素对测量结果的影响主要体现在低频误差上,对高频误差的影响相对较小,搭建的在位检测系统6 h内测量面形误差PV值最大不超过68 nm(约λ/10),RMS值最大不超过15 nm(约λ/40)。
Based on optical element’s high precision in-situ measurement requirements,this paper carries outthe sensitive factor simulation analysis,studies the influence of systematic structural errors and temperature errors onthe measurement results,and designs and builds an in-situ measurement device to carry out measurement experimentsof system temperature change,system repeatability and system stability.The results show that the simulation detectionmodel can be used for plane/spherical/aspherical/free surface,the influence on the measurement results is mainlyreflected in the low frequency error,the high frequency error is relatively small,the maximum PV value of themeasurement surface shape error does not exceed 68nm(aboutλ/10),and the maximum RMS value does not exceed15 nm(aboutλ/40).
