Laser Scanning Mirror

The mirror aperture is large enough to see hundreds of meters ahead of the vehicle.

Laser scanning mirror.

The thickness is optimized to provide low mass while minimizing distortion at high scanning speeds. It is based on industry leading mems technology with novel and precise actuation schemes. High acquisition speed is required to track fast processes especially in living samples. Mar1100 mems 2d laser scanning mirror a 2d mirror with both electrostatic and electromagnetic actuation methods a mems micro electro mechanical system mirror is a tiny solid state mirror mirror on a chip actuated by micro size motors in one or two dimensions.

The laser beam is used to measure the distance to the first object on its path. Scanner mirrors ulo optics offers the lsm series of monocrystalline silicon mirrors for use in galvo based scan heads. In order to position a laser beam in two dimensions it is possible either to rotate one mirror along two axes used mainly for slow scanning systems or to reflect the laser beam onto two closely spaced mirrors that are mounted on orthogonal axes. The mirrors are designed for the use with high power lasers and are sized to accomodate up to 30 degrees of deflection.

This biaxial mems micro electronic mechanical systems mirror operates at 28khz and 60hz with a 40 view angle making it a perfect engine for applications such as laser projection display tof and lidar. A four sided mim scanner can scan 120 degrees wide in front of the autonomous vehicle. Ultimems is founded in new taipei city taiwan in july of 2014. Every scanner consists of rotary motors board of electronics and laser scanning mirror.

Including the group of galvano scanner mirrors where the optical coating a deflection range from 22 58 is taken into account and whose outer dimensions are adapted to the high scanning frequency. The mar1100 is a dual axis mems based scanning mirror targeted for miniature laser projectors and laser steering applications. A mirror tilts vertically. The mirror is crucial optical component in every 2d or 3d galvanometric system thus we pay extra attention to optical and mechanical properties.

The lidar can aim its laser beam in a wide range. Its head rotates horizontally. Low inertia is crucial for laser beam steering systems to attain the highest possible accelerations.
