用液晶电视控制激光束小尺度波前畸变研究
Ｕsing LCTV to control small-scale wavefront distortion of a laser beam

摘要: 将两块液晶电视(LCTV)通过中继成像方式级联，一块用于模拟小尺度畸变波前，另一块用于控制和衰减前面的小尺度畸变，通过环路径向剪切干涉(CRSI)装置对畸变波前的控制结果进行检测，从实验上实现了LCTV对激光光束小尺度波前畸变的控制。从理论上对实验原理进行了分析，给出了补偿后波前存在剩余波前起伏的合理解释。Abstract: 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 smallscale wavefront distortion of a laser beam．
