光劈 meaning in Chinese

optical wedge

After measured the laser energy distribution of kunming slr station , the parameters of this non - gassian and non - spherical symmetric laser beam were deduced according to correlation definition . applying its laws and deduced laser beam parameters , the change of laser beam dirvergence angle was studied in detail when adjusts transmission system focus . moreover , calculation based on these measured data indicates that the laser shaded by the second mirror of telescope is amazingly up to 39 . 8 % , an optical element was designed for the settlement and it worked satisfactorily when put it into practice
之后测量了云南天文台激光的横向能量分布，根据相关定义确定了这束非高斯非球面激光的参数，应用它的传输变换规律和测量参数研究了调焦中激光发散角的变化，并根据测量数据计算出激光发射时副镜挡光比例达到惊人的39 . 8 ，研制出光劈解决这一问题，取得了很好的效果。
