Кинескопный видеопроектор или CRT-проектор … Кинескопный видеопроектор или CRT-проектор (от англ. Cathode Ray Tube, CRT — электронно-лучевая трубка) — разновидность видеопроектора, источником света в котором являются люминофор одного или нескольких кинескопов с повышенной яркостью свечения. До конца XX века видеопроекторы этого типа получили наиболее широкое распространение в небольших аудиториях, поскольку светоклапанные устройства типа «Эйдофор» были чрезвычайно громоздки, дороги и требовали квалифицированного обслуживания.требовали квалифицированного обслуживания.

Típicamente, se utilizan tres tubos de rojo, verde y azul para producir tres imágenes diferentes que deben superponerse perfectamente a fin de obtener una imagen en color. La superposición de imágenes se realiza mediante lentes. Existen varios diseños de lentes, entre los que se incluyen las lentes «directas» a CRT y las .cluyen las lentes «directas» a CRT y las .

, A CRT projector is a video projector that … A CRT projector is a video projector that uses a small, high-brightness cathode ray tube (CRT) as the image generating element. The image is then focused and enlarged onto a screen using a lens kept in front of the CRT face. The first color CRT projectors came out in the early 1950s. Most modern CRT projectors are color and have three separate CRTs (instead of a single, color CRT), and their own lenses to achieve color images. The red, green and blue portions of the incoming video signal are processed and sent to the respective CRTs whose images are focused by their lenses to achieve the overall picture on the screen. Various designs have made it to production, including the "direct" CRT-lens design, and the Schmidt CRT, which employed a phosphor screen that illuminates a perforated spherical mirror, all within an evacuated cathode ray tube. The image in the Sinclair Microvision flat CRT is viewed from the same side of the phosphor struck by the electron beam. The other side of the screen can be connected directly to a heat sink, allowing the projector to run at much brighter power levels than the more common CRT arrangement. Though systems utilizing projected video at one time almost exclusively used CRT projectors, they have largely been replaced by other technologies such as LCD projection and Digital Light Processing. Improvements in these digital video projectors, and their subsequent increased availability and desirability, resulted in a drastic decline of CRT projector sales by the year 2009. As of 2012, very few (if any) new units are manufactured, though a number of installers do sell refurbished units, generally higher-end 8" and 9" models. Some of the first CRT projection tubes were made in 1933, and by 1938 CRT projectors were already in use in theaters.rojectors were already in use in theaters.
