一种基于双折射棱镜的光束扫描角度放大器
摘要：
一种基于双折射棱镜的光束扫描角度放大器，由液晶驱动电路和至少一组双折射棱镜组，所述双折射棱镜组包括多个双折射棱镜单元，所述多个双折射棱镜单元依次排列在同一直线，所述双折射棱镜单元由液晶波片和双折射棱镜组成，所述双折射棱镜由两块光轴相互垂直的双折射晶体组成，同一双折射棱镜的两块双折射晶体楔角相等，所述液晶驱动电路与各个双折射棱镜单元的液晶波片控制连接。本发明采用非机械式角度控制技术，具有扫描精度高、调节速度快、体积小、重量轻和抗干扰性强等一系列优点，并能对入射角度控制范围进行放大，在光学相控阵、激光雷达和空间激光通信等诸多领域具有广阔的应用前景。
摘要（英）：

The invention relates to a birefringent prism based beam scanning angle amplifier, which is composed of a liquid crystal driving circuit and at least one birefringent prism group, wherein the birefringent prism group comprises a plurality of birefringent prism units, the plurality of birefringent prism units are sequentially arranged at the same straight line, each birefringent prism unit is composed of a liquid crystal wave plate and a birefringent prism, the birefringent prism is composed of two birefringent crystals with the optical axes being vertical with each other, the two birefringent crystals of the same birefringent prism are identical in wedge angle, and the liquid crystal driving circuit is in control connection with the liquid crystal wave plate of each birefringent prism unit. The birefringent prism based beam scanning angle amplifier adopts a non-mechanical angle control technology, has the advantages of high scanning precision, high regulation speed, small size, light weight, high interference resistance and the like, can amplify an incident angle control range, and has wide application prospects in the fields of optical phased arrays, laser radar and space laser communication, and the like.
