Abstract
Phase-shifting is one of key technologies in the digital holography or interferometry. Exact and stable phase shifts play an important role in the experimental results. Computer-generated holograph phase-shifting unit based on LC-SLM can produce phase shift with repeatable and high stability. In the system, it is very crucial to encode the computer-generated holograph on LC-SLM. This paper investigates phase-shifting precision and stability as well as diffraction efficiency by using various encoding methods in theory and experiment. The work in the paper establishes foundation that computer-generated holograph phase-shifting unit based on LC-SLM can be applied in the digital holography and interferometry system.
