title = "Surface figure measurements using geometric phase shearing interferometer",
abstract = "In this investigation, we propose a simple radial shearing interferometer using geometric phase lenses. We focus on the analytic approach for surface figure measurements based on the shearing interferometry using the properties of GPLs, and the system instrumentation and characterization with theoretical and experimental concerns. The proposed interferometer in this investigation consists of GPLs to generate two radially-sheared wavefronts and a polarization pixelated camera to simultaneously obtain four phase-shifted interferograms from a single image. In the experiments, the measured results were compared with those of a conventional method, and the proposed interferometer was experimentally verified.",
