Micro laser personal projector

By 1975- Wilfrido Sierra Hernández

Abstract

The proposed research is a study of the technology and applications of personal projectors, small and inexpensive video projection devices intended for use in battery-powered hand-held or wearable products. This research will describe some ways of steering laser beams in one dimension to produce up to a one-meter wide screen. A one dimensional micro laser array will be used to avoid the effect of flickering while projecting an image. The use of a single lens to focus all lasers will save the complexity of collimating each laser independently. At the moment, the Micro Laser Personal Projector is displaying an image of 50 x 480 pixels. A DC brushless motor is used to steer the laser beams vertically. A fixed plano-convex lens focuses all 50 lasers. A piezo-electric device will be used on the future to increase the laser projector's image resolution from 50 x 480 to 200 x 480 pixels. With this image resolution the Micro Laser Personal Projector can be used in communications, entertainment, and medical applications.by Wilfrido Sierra Hernández.Thesis (S.M.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2003.Includes bibliographical references (p. 79-81)
