径向切变干涉仪
Examples
- A cyclic radial shearing interferometer was used to diagnose the wavefront distortion of a laser system and an lcslm ( liquid crysnd spatial ligh modulator ) was used to control it . some results have been summarized as follows : l . according to the theory of scalar quanity diffeaction and the model of the random gaussian phase screen of low frequency wavefront , the effect of the low frequency wavefront with different rms gradient on the focal spot of a laser beam was studied
本论文在激光光束波前畸变检测和控制上进行了新的探索，主要就空间相位调制环路径向剪切干涉仪以及它对波前畸变的检测和液晶空间光调制器及其对中频段波前畸变的控制进行了研究，其研究的内容和取得的成果如下：一、根据标量衍射理论，结合低频波前畸变的高斯随机位相分布模型，研究了不同均方根梯度低频畸变波前对激光光束焦斑聚焦性的影响，并采用描述中频段波前畸变的功率谱密度概念，模拟计算了它对激光焦斑旁瓣的贡献。 - - 2 . in order to accomplish the extraction measuremellt of distorted wavefront on specific plane of a laser beam , a crsi ( cyc1ic radial shearing interferometer ) based on relay imaging technique was built . the experiinental result on this crsi shows it can used to test the spatial mid and low frequency wavefront distortion
二、为了实现激光光束在确定平面上的波前畸变的准确检测，采用中继成像技术建立了一套基于空间相位调制的环路径向剪切干涉波前传感硬件系统，实验证明，它可用于中低频段波前畸变的检测。
