高速摄影能够给出高速变化过程的空间——时间信息。空间信息以图象表示,时间信息通常以分幅频率来说明,而表征时空信息的综合参数总信息量或者时间分辨率则是反映高速摄影水平的一个重要指标。近些年来,随着高速摄影技术的发展,国际上普遍认为,高速摄影是以研究光子为信息载体的科学——光子学的一部分。 High-speed photography can give high-speed changes in the process of space-time information. The spatial information is represented by the image. The time information is usually described by the fractional frequency. The total amount of information or time resolution of the comprehensive parameter that represents the space-time information is an important index reflecting the high-speed photography. In recent years, with the development of high-speed photographic techniques, it is generally believed in the world that high-speed photography is a part of science-photonics that studies photon as the information carrier.
