【摘要】 根据实用性和经济性相结合的原则,我们新研制了一种轻便型的35毫米棱镜补偿高速摄影机。最高摄影频率为500f/s,曝光时间可以短到1/5000秒以下,它可以适用于大部分靶场摄影、人体运动生理研究、风洞中气流的记录等工作。由于它采用了一种同轴快门系统,使摄影机的结构大为简化,整机的尺寸、重量以及价格也较同类型高速摄影机大大减小,主机重量小于8公斤,是同类仪器的1/5～1/10;售价只及同类产品的1/3～1/5,因此它是各靶场旧设备更新的一种理想的高速摄影机。 本文重点介绍了快门的设计和该机在风吹沙、人体运动生理研究中应用所能达到的初步效果。更多还原

【Abstract】 A portable 35mm high speed camera with compensatory prism has been developed. The hightest frequence is 500f/s, the exposure time is less than 1/5000s. It is suitable for studies of the field photography, airflow in a wind tunnel etc. Using of a coaxal shutter system, the camera has a rather simple structure, lighter wieght and smaller dimension than other 35mm high speed cameras. The weight of the camera is less than 8kg and 1/5- 1/10 of other cameras with same type. The price is 1/3- 1/5 of other cameras.This paper explained the design method of the shutter and the applications in studies for wind sand and biomechanics.更多还原
