Development and Calibration of a Radial-Shearing Interferometer
To measure the wavefront of high-power laser with ultra-long focal length, we develop and calibrate a shearing interferometer based on spatial phase modulation. It is experimentally compared with Hartmann-Shack (HS) wavefront sensor and Zygo interferometer. The results show that the shearing interferometer can meet the requirements of precisely measuring wavefront. It has high precision and good repetitiveness.
