ABSTRACT:
A system of retro-illumination for optical valves integrated into a system of projection is constituted by a plane array of slotted fluorescent tubes, parallel to one another, associated with a plane array of longitudinal lenses parallel to the tubes and spaced out substantially by the same pitch. This system is a compact high-output system. It enables an easy gradation of the luminous level as well as the obtaining a trichromatic sequential retro-illumination without moving parts.
