An optical technique is described which is capable of compensating the effects of imperfect spatial coherent illumination on the performance of a modified Mach-Zehnder spectrum analyzer. Methods for experimentally determining the complex mutual coherence function of the illumination using the analyzer are also described. The addition to the system of a calibrated phase shifter controlled by a minicomputer is proposed, which permits the spectral amplitude and phase to be determined automatically in real time.
本文描述了一种光学技术，该技术能够补偿空间相干性不完善的照明对改进型马赫-曾德尔光谱分析仪性能的影响。还介绍了使用该分析仪通过实验确定照明复互相关函数的方法。建议在系统中添加一个由小型计算机控制的校准移相器，这使得能够实时自动确定光谱幅度和相位。
