对Schadin教授提出的转镜分幅相机的鉴别率极限的信息量概念所作的进一步理论探论,构成了本文的大部分篇幅。根据转镜的尺寸和目标的扩散速度所限定的孔径比、鉴别率、分幅速度、有效曝光时间和对光源的要求,提出了一个完全的信息。在这个信息里,可以得到作为象速函数的每幅的平均鉴别率。可以利用这个函数来评定不同型号的转镜分幅相机。此外,还简要地叙述了旋转棱镜和析象管相机、电光快门和变相管的理论研究方面的进展。析象管和变象管所固有的低鉴别率,表明它们用在最高象速区域很有效,而高鉴别率的转镜相机和旋转棱镜动片相机用在比较低的速度区域是非常有效的。
Further theoretical exploration of the concept of the amount of information that Schadin proposed to limit the identification rate of a rotating mirror-framed camera constitutes the bulk of this article. According to the size of the rotating mirror and the goal of the diffusion rate of the aperture ratio, the identification rate, the fractional speed, the effective exposure time and the light source requirements, put forward a complete information. In this information, we can get the average discrimination rate of each piece as a function of the image speed. You can use this function to evaluate different models of rotating mirror framing camera. In addition, the progress of the theoretical research of rotating prisms and resolving cameras, electro-optic shutters and varactor is briefly described. The low discrimination rates inherent in the tubes and tubes indicate that they are effective at the highest image velocities, while high-resolution rotary and rotary-prism motion-picture cameras are very effective at lower velocities .
