一、机械结构二维光辐射扫描台机械结构示意图如图1所示。OA、AB均为可以转动的机械臂,OC为移动扫描台的竖直支撑臂,起着支撑OA和AB及步进电机的作用。O点是整个移动扫描台的扫描原点和中心轴,A为次转动轴,B位置安装光电探测器。在中心轴O位置和次轴位置A装有步进电机1和2,步进 First, the mechanical structure of two-dimensional optical radiation scanning table mechanical structure shown in Figure 1. OA, AB are all rotating arm, OC is the vertical scanning arm support arm, plays a supporting OA and AB and stepper motor role. Point O is the scan origin and center axis of the entire moving stage, A is the minor axis of rotation, and the B position is equipped with a photodetector. Stepper motors 1 and 2 are installed at the center axis O position and the secondary axis position A, and stepping
