摘要
角锥棱镜常被用作光电测距和光电跟踪的合作信标。在一些特殊应用场合中,要求被角锥棱镜反射的光束具有一定的发散角,以实现对远场不同位置处激光器和探测器的全覆盖。标准角锥棱镜不具备对光束发散的功能,但是可以利用角锥棱镜中光束出射点与入射点不同的特性,在标准角锥棱镜前加装平凹透镜来实现对反射光束的发散。采用理论分析方法和几何光学追迹模拟方法分析了利用平凹透镜和标准角锥棱镜实现反射光束发散的可行性,同时研究了反射光束发散半角与入射光束参数和平凹透镜几何参数的定量关系。理论和模拟结果都表明,当入射光束半径小于平凹透镜半径时,反射光束的发散半角随入射光束半径准线性增加;平凹透镜曲率半径越小,反射光束发散半角越大。
Abstract
Cube-corner prism is often applied as cooperative beacon in electro-optical distance measurement and photoelectric tracking. In some special applications, the beam reflected by the cube-corner prism should be with a divergence angle to fully cover both the laser and detector at different locations of the far field. Due to the fact that normal cube-corner prism cannot diverge a beam, the differences of the beam exit point and the incident point of the cube-corner prism are considered and the divergence of the reflected beam can be realized by installing a planoconcave lens in front of normal cube-corner prism. The feasibility of the divergence of the reflected beam by using planoconcave lens and normal cube-corner prism is analyzed by the theoretical analysis method and the geometrical ray-tracing simulation method. The quantitative relationship between the divergence half angle of reflected beam and the parameters of both the incident beam and planoconcave lens geometry is studied as well. Both the theoretical and simulation results show that the divergence half angle of the reflected beam increases quasi-linearly with the incident beam radius when the incident beam radius is less than the radius of the planoconcave lens. The smaller the curvature of planoconcave radius is, the greater the divergence half angle of the reflected beam will be.
