本文提出了一种新颖的干涉方法，用于同时对被测物体进行空间分辨分析，分析相位传输函数以及（单轴）双折射的大小和方向。测量策略是基于相位和偏振的变化以及处理如此获得的干涉图案。这种方法与经典的相移干涉法非常相似，可以在一个测量周期内完成对物体双折射特性及其对入射光相位影响的完整分析。的理论描述的调查方法和他们的实验实施。
This paper presents a novel interferometric method for the simultaneous spatially resolved analysis of an object under test regarding the phase transmission function and the magnitude and orientation of the (uniaxial) birefringence. The measurement strategy is based on variations of the phase and polarization and processing the interference patterns so obtained. With this method, which is very similar to the classical phase-shifting interferometry, a complete analysis of birefringent properties of the object and its impact on the phase of the incoming light can be done in one measurement cycle. The theoretical description of the investigated methods and their experimental implementation are presented.
