摘要/Abstract

摘要： 介绍了基于半导体激光器列阵的距离选通成像系统的总体组成，并针对系统的要求提出三种半导体激光器光束整形设计方案，利用Zemax软件对三种不同结构的整形方案进行了仿真及实验对比分析。结果表明叠层阵列宏透镜准直方案结构简单，对整形透镜的装配精度要求不高，成本低廉，但其对Bar条之间平行性和共面性要求较高; 光纤耦合阵列准直方案的光束发散角最小，但耦合损耗较大; 而基于柱状微透镜准直的叠层阵列光束整形方案具有较高的光收集效率、较小的发散角、工艺复杂性适中，适于远距离激光主动照明成像的工程应用。

Abstract: The whole assembly of the range-gated imaging system based on the semiconductor laser array is introduced， and three kinds of semiconductor laser beam shaping designs are proposed according to the requirements of the system. The simulation and experimental comparative analysis of the three laser beam shaping designs are carried out by using Zemax software. Results show that the stacked array macro lens collimator has the advantages of simple structure, low assembly accuracy and low cost, but it requires high parallelism and coplanarity between bars. The collimation scheme of optical fiber coupling array has the smallest beam divergence angle, but larger coupling loss. The beam shaping scheme of the stacked array based on cylindrical microlens has a high light collection efficiency, a smaller divergence angle and moderate process complexity, which is more suitable for the long-distance active lighting of the laser imaging system engineering.
