摘要

The interferometer can measures accurately a static or dynamic wavefront . It can be done using a system of circular radial shearing interference with spatial phase modulated. Because the method only needs one frame interferogram so that can rejected the effect of vibrations and noises. The wavefront errors measured make adaptive optic system (AOS) that contain a deformable mirror correct the wavefront aberrations again. This paper described a system of radial shearing interference with spatial phase modulation. It is based on the Fourier transform method that the analysis and data processing of the interference fringe pattern with suitable linear carrier. An algorithm of shearing wavefront reconstructed can obtain the original wavefront. The system of diagnostics can check the operation of the AOS and quantify laser beam quality. Finally, the interference experiment and data processing results have been given in this paper.
