Ｕsing LCTV to control small-scale wavefront distortion of a laser beam

Two LCTV are combined by a relay lens.One of the LCTVs is used to simulate a distorted wavefront and the other is used to control and correct this distortion. And the results of simulation and crrection of the distorted wavefront are tested by our CRSI(cyclic radial shearing interferometer), respectively. The results of our testing show that phase-mostly LCTV can be used to control the smallscale wavefront distortion of a laser beam．
