The phase modulation characteristics of liquid crystal SLM (spatial light modulator) and the system for calibrating are proposed. Michelson interferometer is employed for measuring the modulation properties of device. A system interface for operating SLM is designed with VC++ compiler. The initial distortion phase is determined by measuring the reflective interference, and modulation of device is compensated by using our system. By using the LUT (lookup table) data provided by manufacture the wavelength disperse calibration is also achieved successfully.
