Laser Beam Scanning Mirror

Laser beam scanning lbs 24 principles.

Laser beam scanning mirror.

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. Most laser scanners use moveable mirrors to steer the laser beam. However the range tops out at about 3 7m at which points the points dissipate into a circular cloud of noise. Protected aluminum gold silver and dielectric coatings for wavelengths ranging from 250 nm to 10 6 μm.

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 same mems scanning mirror technology acts as a sensor for adas applications. 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. Laser mirrors are designed specifically for use in laser applications.

The mirrors are designed for the use with high power lasers and are sized to accomodate up to 30 degrees of deflection. Creating an image by scanning color lasers thru mems mirrors and modulating the lasers per pixel. 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.

The steering of the beam can be one dimensional as inside a laser printer or two dimensional as in a laser show system. Ulo optics offers the lsm series of monocrystalline silicon mirrors for use in galvo based scan heads. 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. 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.

Dielectric laser mirror coatings optimized for common laser wavelengths provide higher reflection than achievable with metallic coatings. Laser beam scanning for ar display how. Tip tilt mems mirror over competing products. 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.

Many different mirror coating configurations can be applied on scanning mirror substrates. This is true whether the mirror is spinning or stationary at 45 degrees to the laser s beam. There are several major benefits of the mirrorcle technologies inc.
