一、高速摄影技术的发展和动向高速摄影实际上是一种时间放大技术。它是利用快速成像方法,把一个高速瞬变过程的空间信息(用图象来表示)和时间信息(通常以摄影频率来表示)联系在一起记录下来,然后通过慢速度的回放或定格放映,把人眼无法辨认的现象直观地再现出来,供人们仔细观察和研究。例如,美国在进行一次火箭、导弹的发射和溅落实验时,使用多种类型的高速摄影机达100台以上。因此,这一方法已成为科学实验和工程技术中的一项重要检测手段。高速摄影技术的发展,至今已有百余年的历史。近年来,一些新的科学技术成果,如激光技术、全息技术和计算机技术,不断被引进到高速摄影技术领域中来,使这一技术又有了 First, the development of high-speed photographic technology and trends High-speed photography is actually a time-magnifying technology. It uses the fast imaging method to record the spatial information (image) and time information (usually represented by the photographing frequency) of a high-speed transient process, and then through the slow-speed playback or freeze-frame display, The phenomenon of human eyes can not be identified visually reproduced, for people to carefully observe and study. For example, the United States used more than 100 high-speed cameras of various types in carrying out a rocket and missile launch and splash experiment. Therefore, this method has become an important test in scientific experiments and engineering. The development of high-speed photography has been more than one hundred years old. In recent years, a number of new scientific and technological achievements, such as laser technology, holographic technology and computer technology, have been introduced into the field of high-speed photographic technology and made this technology available
