Laser Beam Scanning Mirror

This core technology is the platform for application specific picop scanning engines for use in 3d sensing interactive displays and projected displays.

Laser beam scanning mirror.

However the range tops out at about 3 7m at which points the points dissipate into a circular cloud of noise. There are several major benefits of the mirrorcle technologies inc. Creating an image by scanning color lasers thru mems mirrors and modulating the lasers per pixel. Dielectric laser mirror coatings optimized for common laser wavelengths provide higher reflection than achievable with metallic coatings.

Scanning two axis tip tilt mems mirror or micromirror is an optical beam steering or 2d optical scanning technology that is used in many industries. Laser beam scanning for ar display how. The same mems scanning mirror technology acts as a sensor for adas applications. The thickness is optimized to provide low mass while minimizing distortion at high scanning speeds.

Laser mirrors feature tight surface qualities providing minimal scatter for beam steering applications. Always in focus no blur low persistency 10nsec persistency per laser pixel vs milli seconds of microdisplays viewer comfort low latency one pixel displayed at the time. Most laser scanners use moveable mirrors to steer the laser beam. Microvision s patented picop scanning technology utilizes an ultra miniature mems mirror to scan a modulated laser beam using state of the art control systems.

Additionally the mirrors can lead to a periodic motion like the rotating mirror polygons in a barcode scanner or so called resonant galvanometer scanners or to a freely addressable motion as in servo. The mirrors are designed for the use with high power lasers and are sized to accomodate up to 30 degrees of deflection. Typically coatings come with a secondary reflectivity band for guiding laser beam typically hene 633 nm. Laser mirrors are designed specifically for use in laser applications.

The steering of the beam can be one dimensional as inside a laser printer or two dimensional as in a laser show system. Protected aluminum gold silver and dielectric coatings for wavelengths ranging from 250 nm to 10 6 μm. Laser beam scanning lbs 24 principles. Many different mirror coating configurations can be applied on scanning mirror substrates.

Ulo optics offers the lsm series of monocrystalline silicon mirrors for use in galvo based scan heads. Tip tilt mems mirror over competing products. The scan action is provided by a spinning protected silver first surface mirror from edmond s the cheapest one.
