The isopachics of a birefringent object were obtained as a moiré pattern, see Kihara et al., Appl. Opt. 15, 3025 (1976). This paper describes experiments that separate the isopachics of a birefringent object by using the immersion method real-time polarization holography. The sign of the isopachics is accurately determined in real time by inserting a wave front retarder in the optical path of the illuminating beam and observing the shift of the fringe pattern.
双折射物体的等厚线是以莫尔条纹的形式获得的,见木原等人的文献,《应用光学》15卷,3025页(1976年)。本文描述了通过使用浸没法实时偏振全息术来分离双折射物体等厚线的实验。通过在照明光束的光路中插入一个波前延迟器并观察条纹图案的移动,可以实时准确地确定等厚线的符号。
