| 摘 要： | 为了压缩905nm的半导体激光,以用于远程测距,采用几何光路原理,设计了由两个相互垂直的椭圆柱面透镜组成的准直系统,并在ZEMAX软件的非序列模式下实现仿真。半导体激光器快慢轴的初始发散角为30°和15°,经过柱面透镜后,半导体激光器两个方向的发散角都大大压缩;经准直后,激光束的快慢轴发散角分别为4.4mrad和3.6mrad,基本满足了远程测距的要求。结果表明,椭圆面柱透镜对半导体激光有很好的准直作用。

| Abstract: | In order to compress 905nm semiconductor laser for remote distance measurement，based on geometrical optical theory, an alignment system composed of two vertical elliptical cylindrical lens was designed, then simulation was carried out in the non-sequential mode of ZEMAX software. Initial divergent angles of a semiconductor laser at fast axis and slow axis are 30° and 15° respectively. After passing through the cylindrical lens, these divergent angles became greatly compressed in both directions. After collimation, the divergent angles became 4.4mrad and 3.6mrad at fast axis and slow axis respectively, meeting the requirement of a remote distance detection lidar. The results show that the elliptical cylindrical lenses have good effect on semiconductor laser collimation. |
