液晶空间光调制器是一种用途广泛的器件，广泛应用于现代光学研究的各个领域。采用传统的Twyman-Green干涉仪对Holoye公司生产的冥王星纯相位空间光调制器的相位调制特性进行了测量。早期的条纹漂移通常是人工测量的，由于人为干预，总是存在一些不准确的可能性。提出了用计算机处理干涉条纹和测量移位距离的改进方法，避免了人为误差。
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.
