摘要

    摘要
  • 摘要: 针对激光的快速智能扫描，综合利用晶体的双折射效应和电光效应，提出一种电控集成8行任意扫瞄的高速光扫描方案。主要由三级数字电光偏转器和81的周期性极化电光棱镜组构成，其中3个电光快门和3块双折射晶体构成三级数字偏转器，通过半波电压的控制实现行位置的转换，一定数目的周期性极化电光棱镜级联组成单行偏转器，通过控制电压进行单行扫描，根据电场施加方式可实现数字型或者连续型扫描。利用梯形结构的电光棱镜组设计了最大电压为5.822 kV时，扫描视场为17.256的可通过联机控制进行任意行扫描的高速激光扫描器。
    Abstract: Based on intelligent laser scanning, birefringence effect and electro-optic effect, a scanner for arbitrary scanning in 8 rows is proposed. It mainly consists of a three-order electro-optic deflector and a 81 cascade electro-optic prism group. The three-order electro-optic deflector is composed of three electrooptic shutters and three birefringent crystal plates. The laser beams are switched between rows by controlling half-wave voltage of crystal. The prism group with cascade prisms of optic-axis reciprocatingly scans rows by applied electrical field. Digital or continuous scanning were realized by changing the properties of the applied electrical field. A laser scanner with 17.256 scanning area and 5.822KV maximal voltage was designed by using the cascade electro-optic deflector of trapezium structure. It scans arbitrarily in 8 rows using on-line operation.
