Alliance to develo¥ micromirror-based overhead projector
A collaboration for development of projection products using both lasers and conventional light sources has been announced by Proxima Corp. (San Diego, CA) and Texas Instruments Inc. (TI, Dallas, TX). The companies plan to investigate use of TI?s digital light-processing
subsystems based on its digital micromirror device (DMD), a semiconductor switch that can accurately and precisely control a light source for projection applications. Digital light-processing technology integrates the DMD with digital signal processors, memory, software, and other optical and electronic components to create a digital imaging subsystem. Diode-pumped solid-state microlasers for the project are being developed by Laser Power Corp. (LPC, San Diego, CA). According to Glenn Sherman, chairman and chief executive of LPC, for overhead projection, lasers provide higher brightness, better power efficiency, and better color saturation than conventional sources.
