We extract the 3D phase Δ and the Stokes parameter S 3 of a transmissive anisotropic object spatially using an interferometric PolarCam. Four parallel interferograms with a phase shift of π /2 between the images are captured in a single snapshot and then reconstructed by the four-bucket algorithm to extract the 3D phase of the object. The S 3 is then calculated directly from the obtained 3D phase Δ . The extracted results of Δ and S 3 were compared with those extracted from the non-interferometric PolarCam and the Thorlabs polarimeter, and the results match quite well. The merit of using the interferometric PolarCam is that no mechanical movement mechanisms are included, and hence the Δ and S 3 of the object can be extracted, with high accuracy and within a part of a second (three times faster than non-interferometric PolarCam and Thorlabs polarimeter methods). Moreover, this...

通过使用成像PolarCam直接在空间上解析快照干涉相和Stokes矢量提取

我们使用干涉仪PolarCam在空间上提取透射各向异性物体的3D相位Δ和斯托克斯参数S 3。在单个快照中捕获图像之间具有π/ 2相移的四个平行干涉图，然后通过四桶算法对其进行重构，以提取对象的3D相位。然后直接从所获得的3D相位Δ中计算出S 3。将Δ和S 3的提取结果与从非干涉式PolarCam和Thorlabs旋光仪提取的结果进行比较，结果非常吻合。使用干涉式PolarCam的优点是不包含机械运动机制，因此可以提取物体的Δ和S 3，精度高且在一秒之内（比非干涉式PolarCam和Thorlabs偏振计方法快三倍）。而且这个
