Dove prism

And a multi-channel FORJ is designed using Dove prism.

在此基础上论文采用了一种使用道威棱镜的多通道光纤旋转连接器的设计方法。

An optical system was designed—the red light laser with circularity facular was used as the radiant lamp-house,the beam of light went across the diaphragm and Powell prism,formed a sector light-screen,then went across Fresnel lens,formed a parallel light,the distribution of which was symmetrical.

设计了一套光学系统——以红光点状光斑半导体激光器作为发光光源,光束通过光阑,再经过鲍威尔棱镜形成扇形光幕,然后经过菲涅尔透镜形成一道光强分布均匀的平行光幕。
