We extract the 3D phase △ and the Stokes parameter S3 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 S3 is then calculated directly from the obtained 3D phase △.The extracted results of △ and S3 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 △ and S3 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 method can be applied in the field of the dynamic spectro-interferometric PolarCam and can be implemented using swept-wavelength approaches.
