一、前言 为了观测高速运动目标的瞬息流逝过程,通常有效的方法是采用光学机械式的高速摄影机。但其成本高昂,使用中要消耗大量胶片。更重要的突出缺点是处理时间长,缺乏实时性。然而,这恰是当代一些技术领域中所特别需要的。因此,在七十年代美日等国开展了高速电视摄影方面的研究,到目前为止已发展了用于不同目的的高速电视。在美国高速电视摄影已成为高速摄影领域中一种新的手段之一。
I. INTRODUCTION In order to observe the fast-moving object's fast-moving process, it is usually effective to use optical mechanical high-speed cameras. However, it is expensive and requires a large amount of film to be used. The more important outstanding shortcoming is the long processing time and the lack of real-time performance. However, this is precisely what is needed in some contemporary technologies. Therefore, research on high-speed television photography was conducted in the United States and Japan in the 1970s and so far high-speed television has been developed for different purposes. High-speed television photography in the United States has become a new tool in high-speed photography.
