GE 公司的视频投影器是一种采用光阀管的彩色电视装置(光阀管是分离式的密封电子管型,采用了纹影法原理)。这种装置利用了透明油膜上的衍射光栅,具有利用一个电子枪引起彩色化等独特的优点。下面介绍一下它的工作原理、设计基础和工作特性的概要。
GE’s video projector is a color television set with a light valve tube (the light valve tube is a separate, sealed tube type, using the principle of grain shading). This device utilizes a diffraction grating on a transparent film and has the unique advantage of being colorized using an electron gun. Here’s an overview of how it works, the basics of design, and the features of your work.
