广泛存在着本身不发光或发微光的高速流逝过程,如化工、能源研究中的多相流、体育运动研究中的人体和器械运动等。对于这些目标的高速摄影记录,一种方便的方法是采用闪光摄影,其优点是设备简单,费用低廉,图象清晰,判读简便,结果精确。但目前见于市场的高速闪光摄影设备尚有许多不足和不甚理想的地方。一是只有 There is a wide range of high-speed passing processes that do not emit light or shimmer, such as multiphase flow in chemical engineering and energy research, human body and equipment movement in sports research, and the like. A convenient way for high-speed photographic recording of these targets is flash photography, which has the advantages of simple equipment, low cost, clear images, easy interpretation and accurate results. However, there are still many inadequacies and unsatisfactory places for the high-speed flash photographic equipment currently on the market. First, only
