本文旨在讨论一种能在APPLEⅡ微机及相应的性能价格比较低的微机上(內存容量小于64KB)运行的干涉图处理软件算法。该算法沿干涉条纹中心线抽样,以较少的初始数据,用最小二乘法求取最佳参考波面,并给出各点OPD值及P—V,RMS值,並用曲面样条函数的拟合和内插获得较逼真的OPD分布三维立体图及等值线图,以使这种干涉计量自动分析技术能以较低的成本为一般光学工厂和车间所接受。 The purpose of this article is to discuss an interferogram processing software algorithm that runs on APPLE II computers and their corresponding low-cost PCs (with less than 64KB of memory). The algorithm samples along the center line of the interference fringes, uses the least squares method to get the best reference wave surface with less initial data, and gives the OPD value and P-V and RMS value of each point, and uses the fitting of the surface spline function And interpolation to obtain more realistic OPD distribution of the three-dimensional maps and contour maps, so that the automatic interferometry technology can be lower cost for the general optical factory and workshop acceptable.
