转镜扫描高速摄影系统的信息量

AMOUNT OF INFORMATION OF ROTATING MIRROR HIGH-SPEED PHOTOGRAPHICAL SYSTEMS

结合转镜扫描高速摄影系统,本文对信息量和信息率两个指标描述系统性能的价值作了评价,讨论了实际系统中影响它们的复杂因素,以及简化计算它们的必要性和可能性。

In this paper, with the discussion of rotating mirror scanning highspeed photographical systems, the role of amount of information and rate of information in assessing the quality of a high-speed photographical system is examined, the complicated factors, in real photographical system which influence the amount of information and rate of information are analysed, and the necessity and possibility for simplifying their calcula tion is also discussed.
