目前,国内许多部门和单位都选用了“PENTAZET35”型高速摄影机,将其用于科学研究和工程技术中。这种摄影机在摄影时胶片是连续通过片窗的。为了补偿由于胶片运动所产生的影像模糊,该摄影机采用了旋转内镜鼓的光学补偿方法。实践证明,由于胶片的传输速度高,当摄影机的工作条件得不到基本保证,调试不当或操作不符合要求时,很容易产生断片。断片后如不能及时停机,胶片将由继续转动的齿轮带动,紧紧缠绕在输片齿轮上,挤塞在机器内。有时甚至由于摩擦生热使胶片燃烧,放出大量烟
At present, many domestic departments and units have chosen “PENTAZET35” type of high-speed cameras, used in scientific research and engineering. The film is continuously passed through the film window when the camera is in photography. In order to compensate for the image blur caused by the movement of the film, the camera uses an optical compensation method of rotating the endoscopic drum. Practice has proved that due to the film transfer speed is high, when the camera’s working conditions are not guaranteed, commissioning improper or operation does not meet the requirements, it is easy to produce fragments. If the film can not be shut down in time, the film will be driven by the rotating gear and tightly wrapped around the sprocket, which is jammed in the machine. Sometimes, the film is burned by frictional heat generation and emits a lot of smoke
