Paper Abstract

Speckle can seriously degrade image quality in laser-illuminated projection displays. Various solutions appropriate to small microdisplay-based projectors are presented. Illumination optical system and projection optical system design are discussed in order to better understand the critical constraints of size, power consumption, optical efficiency, and performance. DYOPTYKA's innovative solution, using a phase randomizing deformable mirror, is described.
