Phase Retardation Analysis in a Rotated Plane-Parallel Plate for Phase-Shifting Digital Holography

Abstract

In this paper, we detail a phase-shift implementation in a rotated plane-parallel plate (PPP). Considering the phase-shifting digital holography application, we provide a more precise phase-shift estimation based on PPP thickness, rotation, and mutual inclination of reference and object wavefronts. We show that phase retardation uncertainty implemented by the rotated PPP in a simple configuration is less than the uncertainty of a traditionally used piezoelectric translator. Physical experiments on a phase test target verify the high quality of phase reconstruction.

Analysis of cellular response to photodynamic treatment with Radachlorin photosensitizer by means of quantitative phase microscopy using highly coherent and partially coherent light sources

“…37 Reconstruction of the target phase image is somewhat similar to phase shifting interferometry, which is often used for accurate reconstruction of the complex amplitude of object wave when coherent laser sources are used. [38][39][40] The optical layout of the setup is shown in Fig. 3(a), the typical phase contrast images of HeLa cells are shown in Fig.…”
