rhombic prism meaning in Chinese

菱形棱镜
斜方柱

This paper designs an optical system based on above to measure the small angle of the laser beam . a non - polarized beam splitter ( npbs ) is used to split the incident beam into two branches , and a rhombic prism agglutinated by two right - angle prisms is placed to realize total internal reflection twice in each branch . it not only improves the measurement sensitivity and linearity , but also increases antinoise ability by the differential optics
本文正是基于这一原理设计了测量光束微小偏转角的光路系统,用消偏振分光棱镜将入射光分为两路,并在两路分别用两个直角棱镜组成的斜方棱镜来实现两次全内反射,不但提高了测量灵敏度和线性,还利用差分光路的特点提高了抗干扰能力。
