Study on the Phase Modulation Characteristics of Liquid Crystal Spatial Light Modulator
A special Twyman-Green interferometer is designed to measure the phase modulation characteristics of liquid crystal spatial light modulator (LC-SLM), namely, the relationship between phase shift and gray value (applied voltage). By measuring a reflective LC-SLM produced by BNS (Boulder Nonlinear Systems), it is indicated that the LC-SLM has linear phase response within a gray value range between 60 and 200, and the RMS deviation between the average phase and the spatially resolved phase measurements increases with the gray value but is always less than λ/10.
