3Digital holographic shape measurement using Fizeau microscopy显示文摘We present a Fizeau interferometer using a microscopic objective as a tool for surface contouring without the need for a numerical lens for reconstruction. The interferometer is associated with a telescope system to feature the object with collimated light. The experiment is conducted on two objects possessing different step heights.The phase maps from the captured off-axis holograms are calculated numerically, which allows us to deduce the contours of the objects. The great advantages of the presented technique are that it can be done in real time and there is no need for numerical lenses for micro-objects reconstruction.D.G.Abdelsalam Junwei Min Daesuk Kim Baoli Yao 2015Chinese Optics Letters2015,13,10:0

5Direct Spatially Resolved Snapshot Interferometric Phase and Stokes Vector Extraction by Using an Imaging PolarCam显示文摘We extract the 3 D phase△and the Stokes parameter S3 of a transmissive anisotropic object spatially using an interferometric Polar Cam.Four parallel interferograms with a phase shift ofπ/2 between the images are captured in a single snapshot and then reconstructed by the four-bucket algorithm to extract the 3 D phase of the object.The S3 is then calculated directly from the obtained 3 D phase△.The extracted results of△and S3 were compared with those extracted from the non-interferometric Polar Cam and the Thorlabs polarimeter,and the results match quite well.The merit of using the interferometric Polar Cam 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 Polar Cam and Thorlabs polarimeter methods).Moreover,this method can be applied in the field of the dynamic spectro–interferometric Polar Cam and can be implemented using swept-wavelength approaches.Dahi Ibrahim Daesuk Kim 2020Chinese Physics Letters2020,37,7:0
