Phase retrieval technique from regions of unresolvable fringe density using Phase Shifting Interferometry and Liquid Crystal on Silicon (LCOS) Spatial Light Modulator (SLM)

Abstract

This paper presents a simple method to recover phase information from regions of unresolvable fringe density, specifically, at the camera corners, where interference fringes are not resolved by the camera using Phase Shifting Interferometry and Liquid Crystal on Silicon (LCOS) Spatial Light Modulator (SLM). The method works well with wavefront compensation. This work is a continuation and advancement of reported research work [14].
