Paper Abstract

A slightly off-axis digital holography is proposed using polarization technology for quantitative phase imaging. Employing a nearly common-path flipping interferometry configuration, our approach realizes interference by flipping the relative position of a sample and reference beam. Using polarization modulation, the sample beam is converted to be 45° linearly polarized, and the reference beam is modulated to be circularly polarized. By setting a polarizer placed before the CCD camera with angles of 0° and 90°, two carrier holograms with phase shifts of 0 and π/2 can be obtained, respectively. Then, the phase distribution of the sample can be retrieved using a fast slightly off-axis digital holography reconstruction method. Theoretical analysis and experiments are carried out to demonstrate the validity and stability of the proposed method.
