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像的。胶片在15米/秒的速度下必须与转镜反射的像保持严格的同步,否则就会产生像移出现虚像。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,将直接影响到成像的质量。 First, an overview Rotary mirror optical compensation high-speed camera (principle see Figure 1) film is 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 is driven by a set of gears. The error of gear transmission, as well as the vibration and instability caused by high-speed operation, will directly affect the quality of imaging.
