Engineering samples for LBS laser beam scanner for AR smart glasses
TriLite in Austria has launched form factor engineering samples of its laser beam scanner (LBS) for AR smart glasses.
The Trixel 3 LBS from TriLite combines the display engine, control electronics and Trajectory Control Module (TCM) software for AR smart glasses.

By providing all the system-level components required for evaluation, application development and test, the samples enable rapid prototyping of augmented reality (AR) systems.
Trixel 3 is the world’s smallest projection display with a low power consumption of under 320 mW for all-day use and 15 lumens display.
The engineering samples are based around the Trixel® 3 optical display engine, which combines a single 2D MEMS mirror, RGB laser diodes and all optical components. The LBS nit is supplied pre-calibrated for colour alignment and distortion correction. The display engine and the driving electronics are now in the form factor for use in smart glasses, which is important for customers to rapidly design and prototype their AR systems using the Trixel 3 technology.
“With these engineering samples now available, we are very close to the final specification of Trixel 3,” said Dr. Dietmar Gleispach, COO at TriLite. “This represents a key milestone for having a qualified product on a qualified production line according to TriLite’s APQP and enabling ramp up later this year with lead customers.”
TriLite’s latest TCM software is supplied with the engineering samples. TCM is part of TriLite’s ‘software-defined display’ approach, which shifts complexity from the hardware to the software domain. It uses proprietary algorithms to ensure optimum image quality and minimum latency, control position and brightness at subpixel accuracy, and to assure low power consumption.
The TCM software runs on a host processor, and the engineering samples include a suitable evaluation host as well as the driving electronics for connecting the Trixel 3 LBS to the host. in the AR smart glasses This includes the TriLite Image Controller (TIC), and drivers for the RGB laser diodes and the MEMS mirror.
