无论是号称科学“千里眼”的传真术,还是人们日常文化、生活中的摄影术,都离不开影象的记录和显示.特别是二十世纪中期,随着电子工业、激光技术、宇航事业等的飞速发展,迫切要求有解象力高、信息贮存密度大、易于操作、能重复使用和能实时记录、显示的录象材料和技术.1957年格林(W.E.glenn)基于四十年代的油膜光阀映象的原理,发展了热塑录象技术. 热塑录象的发展四十年代费许(Fischer)等人进行了油膜光阀放映电视象的研究工作,1946年出现了艾多福(Eido-phor)投影电视机.但碍于艾多福油膜光阀是呈液态的,其分辨率不高,信息记录密度较低,信息也不能
Whether it is known as the science of “clairvoyance” telephony, or people’s daily culture, life photography, are inseparable from the record and display images, especially the mid-twentieth century, with the electronics industry, laser technology, aerospace industry Such as the rapid development of the urgent need to have a strong imagination, information storage density, easy to operate, can be reused and can be recorded in real time, display video materials and technology .1957 Green (WEglenn) based on the forties film light valve The principle of the image, the development of the thermoplastic video recording technology. The development of thermoplastic video In the 1940s Fischer et al (Fischer et al. Conducted a research on the film light valve projection television, 1946 appeared Eido -phor) projection TV.But due to the Ai Duofu film light valve is liquid, its resolution is not high, the information recording density is low, the information can not
