Polarimetric Calibrated Robust Dual-SLM Complex-Amplitude Computer-Generated Holography

1 July 2023

Polarimetric Calibrated Robust Dual-SLM Complex-Amplitude Computer-Generated Holography Liquid crystal on silicon (LCoS) is a widely used spatial light modulator (SLM) in computer-generated holography (CGH). However, the phase-modulating profile of LCoS is often not ideally uniform in application, bringing about undesired...
