Laser Beam Scanning Mirror

Creating an image by scanning color lasers thru mems mirrors and modulating the lasers per pixel.

Laser beam scanning mirror. Protected aluminum gold silver and dielectric coatings for wavelengths ranging from 250 nm to 10 6 μm. The same mems scanning mirror technology acts as a sensor for adas applications. 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. The mirrors are designed for the use with high power lasers and are sized to accomodate up to 30 degrees of deflection.

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. The thickness is optimized to provide low mass while minimizing distortion at high scanning speeds.

Most laser scanners use moveable mirrors to steer the laser beam. 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. Tip tilt mems mirror over competing products.

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 steering of the beam can be one dimensional as inside a laser printer or two dimensional as in a laser show system. Laser beam scanning lbs 24 principles. 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. The scan action is provided by a spinning protected silver first surface mirror from edmond s the cheapest one. Ulo optics offers the lsm series of monocrystalline silicon mirrors for use in galvo based scan heads. Typically coatings come with a secondary reflectivity band for guiding laser beam typically hene 633 nm.

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. However the range tops out at about 3 7m at which points the points dissipate into a circular cloud of noise. Laser mirrors feature tight surface qualities providing minimal scatter for beam steering applications.
