Mirrorcle Technologies MEMS devices address a wide range of applications that require optical beam steering. As optical scanning or beam steering appears in various industries and numerous applications, our scanning mirrors are most beneficial in those applications that require miniature, high speed, low-power, or low-cost solutions. Some of the applications of MirrorcleTech devices that are currently under development are listed here. Projection Displays Low-cost and readily deployable video displays on glass and other transparent surfaces (e.g. car windshield HUD.) Miniature, hand-held, and battery-run full-color video projection displays at SVGA resolution. Single- or multi-color vector-graphic projection displays

3D Scanning and Ladar Imaging

• Laser vision for robots (read related article.)
• Devices provide precisely positioned laser spot or laser line for camera imaging.
• Non-contact 3D scanning of solid objects to obtain their precise measurements and computer models.
• Various standard techniques can be used with the advantage of portability and low cost with our MEMS devices.

3D Tracking and Position Measurement

• Position measurement for gaming controllers and related human-computer interfaces.
• High end 3D measurement units for contstruction and other industrial uses.
• Our device was recently used in a demonstration by National Instruments at the NI Week 2009 event in Austin, TX. See the video of fast laser tracking based on NI's FPGA hardware and Mirrorcle Technologies MEMS mirror. (Actual demonstration begins at ~3:20.) New!
