光束

The sun’s gravitation was bending the beam of light.

太阳的引力使束弯曲。

In the usual lives, laser beam need either propagation through optical system to interreact with other material or in order to satisfy the parameter require.

在实际应用激束要通系统后与物质相互作用或为了满足参数要求需要通系统加以变换。

Satellite retroreflector is used as laser ranging cooperative target to improve the intensity of reflected beam, which has close relationship with processing parameters of the retroreflector.

卫星角反射器作为激测距系统的合作目标, 其主要作用在于提高地面接收机范围内反射束的能量密度。

Based on the double refraction principle of outgoing beam in the biprism,the displacement method for measuring the small angle of biprism is presented.The error of this method is also discussed.

利用双棱镜引起出射束方双的原理,提出了一种位移法测量玻璃双棱镜微小底角的新方法,介绍了测量的基本原理,讨论了测量误差.
