Measuring Algorithms of Laser Far Field Flare Energy Density Based on Detector Array Method

针对靶场试验装备布局很难做到激光器与阵列面垂直的实际情况,分析了激光探测器阵列系统处理激光光斑能量密度算法的不足。根据激光束照射靶面的倾斜角,研究了激光束与每个探测器形成夹角的计算方法,并推导出了具体的余弦角计算公式,对激光光斑每一点的能量密度进行了相应的修正计算,通过试验应用,验证了该算法在激光远场光斑测量中能够有效提高光斑能量密度的处理精度。

The shortcomings of the far field laser flare energy density calculation of laser detector array system in the actual application are analyzed in this paper. According to dip angle of the laser beam irradiated at the target surface, each angle in- cluded between detector and beam is calculated. Every bit of energy density of laser spot is corrected. Through the test this correction algorithm can effectively improve the far field flare energy density of the processing precision.
