为了在间歇式高速电影摄影机工作时实现跟踪取景,其中方法之一是采用反光叶子板的结构。它的好处是没有视差,不降低画面的曝光能量。反光叶子板结构在普通电影摄影机中大量采用,但在高速下,特别对于200幅/秒以上的摄影机还未曾采用过。考虑到在高速情况下结构的强度刚度,以及加工面形等问题,我们先后设计了几种不同材料和结构的反光叶子板:硬铝镶玻璃;硬铝表面镀硬铬;全玻璃等,并分别进行了部分实验。
One of the ways to do this is to use the structure of a reflective leaf for tracking shots while working on intermittent high-speed movie cameras. Its advantage is that there is no parallax, does not reduce the exposure energy of the picture. Reflective leaf structure is widely used in ordinary movie camera, but at high speed, especially for more than 200 / second camera has not been used before. Taking into account the strength and stiffness of the structure under high-speed conditions, as well as the processing of surface shape and other issues, we have designed several different materials and structures reflective leaf board: hard aluminum glazing; ; all glass, etc., and were part of the experiment.
