Abstract
AbstractThe rapid evolution of digital projector technology in the recent years, one of the major trends is light, thin, and small portable projector. The research is an extended work based on Texas Instruments Inc. DLP (Digital Light Processing) projection technology which discusses the feasibility on how to shrink optical system in non-imaging and imaging optical designs. Another key feature is exploiting laser instead of conventional UHP lamp as the illuminator.During the experiment, the prototype is modified from an existing commercial DLP projector bought from the projector market. The laser projector should be able to project image on the wall after the modification. The article will describe the detail process of the integration including optical simulation to design a small achromat doublet projection lens, laser illuminator design, laser beam shaping, and electronic controller design to control lasers in color-sequential mode. Eventually, evaluate the each performance index after the laser projector is successfully in operation.
