适用于激光合成器的激光光斑中心检测
|
摘要
为了在工程中合成能量高的激光光束,需对激光合成器中的多路高功率激光光斑中心进行实时准确检测。针对采集到的激光合成器中激光光斑的大面阵大目标等特点,提出用两步检测法对激光光斑中心进行检测。通过对现有激光光斑中心两步检测法的分析比较以及通过计算机仿真和实验验证来获得一种适用于激光合成器的激光光斑中心检测的算法。研究结果表明现有的激光光斑中心两步检测算法大多针对小面阵小目标低功率且多为理想光斑的情形,而采用本文提出的算法可以分别针对激光合成器中采集到的饱和光斑和非饱和光斑做实时准确的检测,具有工程实用价值。
In order to synthesize high energy laser beam in engineering,it is necessary to detect the high power laser spot center in laser synthesizer. According to the characteristics of the laser spot in the laser synthesizer,the two-step detection method is proposed to detect the laser spot center. Through the analysis and comparison of the current two-step detection methods,a new algorithm for laser spot detection is obtained by the computer simulation and experimental verification. The results show that the existing two-step detection algorithms are suitable for small target,small array,low power,ideal laser spot,but the proposed algorithm is suitable for real-time and accurate detection in the saturated and non saturated spots,which has practical value in engineering.
