本文介绍的装置是为了研究一定范围内物体运动模态用的。该装置乃仿效在底片上多次暴光成像的方法,在照相机镜头前端加装一个带孔的回转屏作快门。对运动物体拍摄后,其影像将依次错开显示于同一底片上。测出各影像间的位移和时间,就可对被测物体进行运动学和动力学分析。该装置结构简单、操作方便、性能可靠、成本低廉。 This article describes the device is to study a certain range of objects used in the movement mode. The device is to follow the repeated exposures in the film imaging method, the front of the camera lens with a perforated rotary screen for the shutter. After taking pictures of moving objects, the images will be displayed on the same negative film in turn. Measured the displacement and time between the images, the object can be measured kinematic and kinematic analysis. The device has the advantages of simple structure, convenient operation, reliable performance and low cost.
