摘要：
Liquid crystal spatial light modulator is a versatile device to be used in different areas of modern optical studies. The traditional Twyman-Green interferometer is used to measure phase modulation characteristics of PLUTO phase-only spatial light modulator produced by Holoeye Company. Earlier fringe shift used to be measured manually due to which there is always some possibility of inaccuracy created by human intervention. We propose improved method to process interference fringes and measure shift distance by computer to avoid human error.
