高速摄影对于物体运动过程的观察极为重要,因为它能使整个进程按原样再现出来,资料形象,结果可靠.对于某些持续时间极长或特短以致肉眼无从目睹的运动过程也能使之再现,并可测量和研究.因此,随着工农业的发展,高速摄影机的应用越来越广.目前,国内外高速摄影机的种类很多,按速度可分为低速、中速、高速和超高速.重庆煤炭科学研究所现用的是东德盼他捷—35型高速摄影机属中速一类,拍摄频率由250张/秒到40000张/秒,频率适中,得到的底片可直接放映能够将时间放大,并能看清细节.
High-speed photography is extremely important for observing the movement of an object because it enables the entire process to be reproduced as it is, with a visual representation of the data and a reliable result. It is also reproducible for certain moving processes that are extremely long or short in duration and unobtrusive to the naked eye Therefore, along with the development of industry and agriculture, the application of high-speed cameras is more and more widely. At present, there are many kinds of high-speed cameras at home and abroad, which can be divided into low speed, medium speed, high speed and super speed according to the speed. Coal Research Institute is currently using the East Germany hope him Czech -35 high-speed camera is a medium speed, shooting frequency from 250/40000 / second, the frequency is moderate, the film can be obtained directly show the time to zoom , And can see the details.
