Laser-Illuminated Three-Panel LCoS Projector with a Vibrating Diffractive Microlens-Array Beam Shaper

摘要

A RGB lasers illuminated three-panel LCoS projector has been developed to demonstrate the viability of a double-side microlens array as a diffractive beam shaper. By oscillating the beam shaper, both the uniformity and speckle pattern were significantly improved. The contrast ratio of the image speckle was measured to be below 8%.
