Micro-beamer based on MEMS micro-mirrors and laser light source

This paper presents a complete portable laser-based projection system using two one-dimensional magnetic actuated MEMS linear scanning micro-mirrors. Dedicated high speed electronics was developed to drive the MEMS, detect the mirror scanning position at any time and synchronize the two mirrors and the laser pulsation. The achieved projection system head is 3 cm3 and is able to project static images and videos with projection size of 50 cm diagonal at 50 cm distance with 32x32 px resolution, the resolution is only limited by current optical setup. The circuit building blocks itself can project image with resolution up to QVGA (320x240 px), suitable for information display applications. © 2009.
