为了解决激光束扫描的高分辨率和动作快的问题,通常采用鼓形多面体反射镜的机械转向器。近来,由于对有效地利用激光能量和发散角提出了更高的要求,这就迫使人们探索和研制新的系统以满足这一要求。已制成的跟踪扫描装置,当投射到多面体反射镜 In order to solve the problem of high resolution and fast motion of the laser beam scanning, a mechanical steering gear of a drum-shaped polygon mirror is usually used. Recently, higher demands have been placed on the efficient use of laser energy and divergence angle, forcing people to explore and develop new systems to meet this requirement. The tracking device has been fabricated when projected onto a polygon mirror
