光干涉测量中光程差的加权最小二乘估计

Weighted-Least-Squares-Estimation of Optical Path Difference in Optical Interferometry

根据加权最小二乘估计的原理,分别导出了光干涉i典l量中,单通道检测和多通道检测情况下光程差的估计值及估计的方差,并对它们的应用作了一些讨论沿。

The estimations of optical path difference and its variance in optical interferometry are derived from the principle of weighted-least-squares-estimation for both single-channel and multi-channel detection, and some discussions about their application are also given in this paper.
