Abstract

Based on the Schardin's formula and the camera designing procedures, the expression of amount of information for high-speed rotating mirror photography system is obtained. This paper proposes a new concept of evenness of amount of information and takes the evenness of information as an additional standard which evaluates system quality. It shows that the amount of information depends on the solection of working angle scale and section shape of rotating mirror besides the maximum edge velocity of rotating mirror. As the wide application of high-speed camera, discussion of its designing method and evaluating criterion continually deepen. One of evaluating criterion of high-speed camera is amount of information. Many schlors discuss this problem from fundamental theory. Starting from the designing method, this paper discusses the amount of information and the evaluating criterion, therefore to find better evaluating criterion.
