Laser Beam Scanning Mirror

Typically coatings come with a secondary reflectivity band for guiding laser beam typically hene 633 nm.

Laser beam scanning mirror.

Many different mirror coating configurations can be applied on scanning mirror substrates. Light from one multiple lasers is combined into a single beam beam is relayed onto mems scanning mirror s mirror s scan the beam in a raster pattern a projected imageis created by modulating the lasers synchronously with the position of the scanned beam 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.

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. The thickness is optimized to provide low mass while minimizing distortion at high scanning speeds. 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. This is true whether the mirror is spinning or stationary at 45 degrees to the laser s beam.

The scan action is provided by a spinning protected silver first surface mirror from edmond s the cheapest one. 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. Laser beam scanning for ar display how. Laser mirrors are designed specifically for use in laser applications.

This core technology is the platform for application specific picop scanning engines for use in 3d sensing interactive displays and projected displays. Dielectric laser mirror coatings optimized for common laser wavelengths provide higher reflection than achievable with metallic coatings. Creating an image by scanning color lasers thru mems mirrors and modulating the lasers per pixel. Most laser scanners use moveable mirrors to steer the laser beam.

A mems scanning mirror is the core part of our laser beam scanning lbs display technology which can together with relay optics be used to build and realize hud 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. There are several major benefits of the mirrorcle technologies inc. The mirrors are designed for the use with high power lasers and are sized to accomodate up to 30 degrees of deflection.

Ulo optics offers the lsm series of monocrystalline silicon mirrors for use in galvo based scan heads. However the range tops out at about 3 7m at which points the points dissipate into a circular cloud of noise. The same mems scanning mirror technology acts as a sensor for adas applications.
