摘要
采用计算机仿真技术模拟了近柱非球面的正入射式检测装置。获取并分析了理想近柱面和理想柱透镜下的干涉图。讨论了降低干涉图P-V值的方法以及不同面形的近柱面在该装置下的可检性。
In this paper, the testing set for near-cylindrical surfaces is simulated by computer. The interferograms under ideal near-cylindrical surfaces and ideal cylindrical lens are got and analyzed. The method to reduce P-V value of the interferograms and the testability of all kinds of near-cylindrical surfaces under the testing set are discussed.
