先指出了放映大屏幕电视所带来的一些问题,简单地比较了现在已知的几种方案,包括摄制胶卷再放电影的方案,放映显象管荧光屏的方案,利用激光扫描光阀的方案,和油膜散光电子阀Eidophor方案。油膜散光电子阀是目前应用的唯一的实时型方案, 它的缺点是笨重而庞杂。本文着重介绍一种可行的简练方案,是利用 KD_2PO_4 晶体的电光效应,作成一种新的偏光电子阀。在欧洲和美国正沿用这一效应试制各种型式的阀管。作者在法国电子与物理研究室试制成一种偏光电子阀管,TITUS,在此叙述较详。在这个阀管里,晶体被降低到居里温度-60℃进行工作,它的突出特点是,能放映出没有闪烁的图象。初步试验结果表明,它可以得到满意的分辨率和反差度。
First pointed out the big screen TV show some of the problems caused by a simple comparison of several programs now known, including the filming of film re-release film program, the projection screen fluorescent screen program, the use of laser scanning light valve program , And oil film astigmatism electronic valve Eidophor program. Oil film astigmatism electronic valve is the only real-time application of the program, its disadvantage is bulky and complex. This article focuses on a feasible concise program, is the use of KD_2PO_4 crystal electro-optic effect, to create a new polarized electronic valve. In Europe and the United States are using this effect trial of various types of valve. The author at the French electronics and physics laboratory pilot made a polarized electronic valve tube, TITUS, described in more detail. In this valve tube, the crystal is lowered to a Curie temperature of -60 ° C for operation, and its outstanding feature is that it can display a non-flickering image. Preliminary experimental results show that it can be a satisfactory resolution and contrast.
