| 摘 要： | 在分析现有的激光远场能量密度分布测试方法的基础上提出了一种新的测试方法.采用激光束照射漫反射靶,CCD相机对靶上激光光斑成像并在靶面上布置能量计探头以获取能量抽样绝对值的方法进行激光束远场大气传输后空域分布测试.从基本组成、测试原理、试验结果等方面对新测试方法进行了分析研究,并通过采用532nm脉冲激光照射1Km外的漫反射靶的实验对新测试方法进行了可行性验证,获得了远场激光光斑的图像和能量抽样值.

| Abstract: | The detection mehtods of far-field laser energy density distribution was analyed,and a new detection method was proposed.Using laser beam shoot to the reflex tartget board,taken image of the laser spot on the board by CCD camera and surveyed the sampling energy value by energy detector which lies on the board,the laser beam propagating through amosphere far-field distribution was obtained.The basic module and the detection principle etc.of new detection method was analysed,and verified In experiment,532 nm pulse laser shoot to the reflex tartget board,the laser far-field spot image and the sampling energy value was gained. |
