Speckle Suppression by Controlling the Coherence in Laser Based Projection Systems
Abstract
In this paper, the relationship between the coherence and the speckle contrast in a laser-based projection display system is studied with the consideration of human visual percept. By using a varifocal liquid-crystal lens and a monochromatic charge-coupled device (CCD), a system which is used for simulating a human eye is set up to record the speckle pattern. An efficient method for controlling the spatial coherence by using a dielectric …
