一、概述旋转反射镜光学补偿式高速摄影机(原理见图1)胶片是在连续输片的过程中感光成象的。胶片在15米/秒的速度下必须与转镜反射的象保持严格的同步,否则就会产生象移出现虚象。实现这种同步运动,是靠一组齿轮来传动的。齿轮传动的误差,以及高速运转中产生的振动和不平稳,将直接影响到成象的质量。 First, an overview of rotating mirror optical compensation of high-speed camera (principle see Figure 1) film is a continuous film in the process of imaging. Film at 15 m / s speed must be mirrored with the rotating mirror to maintain strict synchronization, otherwise it will have to move like a virtual image. To achieve this synchronous movement, it is driven by a set of gears. Gear transmission errors, as well as high-speed operation of the vibration and instability, will directly affect the quality of imaging.
