New LEDs improve the quality of illumination of full-color holograms recorded with red 660 nm, green 532 nm and blue 440 nm lasers

Abstract

This paper discusses the main requirements in today's full-color holograms illumination and evaluates the last generation of LEDs, the actual best light source to render properly the colors of the holograms and in particular those recorded with red 660 nm, green 532 nm and blue 440 nm lasers. This paper presents also the first prototype of lamp designed especially for this kind of holograms.
