Formation of a television image with the aid of a laser electron-beam tube under line scanning conditions

A laser electron-beam tube was used to form a projection-television image in a system in which scanning with an electron beam across the laser screen produces the television line scan, and a rotating prism or mirror was used to provide the frame scan. Images of 1 m² area were obtained in green (λ = 500 nm) and red (λ = 620 nm) light. The advantages of this type of laser projector were: less stringent requirements in respect of the technology of fabrication of semiconductor screens and simplification of the system used to superimpose monochrome images to form a color image.
