Photoluminescent conversion of laser light for black and white and multicolor displays. 2: systems.

Recent technological developments permit the modulation and scanning of laser beams at rates comparable with those of electron beams in television receivers. This accounts for much of the current interest in laser illuminated display systems which are not constrained in size, as is the cathode ray tube, by the necessity of a vacuum enclosure. The purpose of the present work is to show how photoluminescent materials can be used in conjunction with recently developed acoustooptic deflectors and modulators to achieve high quality laser display systems.

Photoluminescent conversion of laser light for black and white and multicolor displays. 1: materials.

A number of photoluminescent materials have been found to have properties that make them extremely useful for improving the quality of laser displays as well as offering simplifications for multicolor systems. The principal function of these materials is that of color conversion when coated onto a laser illuminated viewing screen. A secondary, yet significant, role is that of rendering the converted light incoherent.
