摘要
简单介绍了一种二维定心偏转激光扫描器件的工作原理和结构设计 ,重点比较了两种不同摆角测量方式的优劣 ,包括它的计算模型、光学系统构造以及采用光电位置传感器 (PSD)
The principle and structure design of a 2 DOF tip/tilt laser scanner is introduced and two different methods to measure the 2 DOF deflection angle are compared.The aspects of the measurement system using PSD are discussed,including its basic principle,optical system and signal processing circuit.The system now can reach a wide scanning range of 30° with resolution of 0.01°.
