MEMS ScanAR technology enables fast development of high-performance Augmented Reality glasses through a reference design and a manufacturing ecosystem.

MEMS micromirror solutions are typically used in laser beam scanning systems (LBS) to project visible images or infrared patterns. These solutions work by deflecting laser beams emitted from laser diodes to project images onto the required field of view. The beam deflection is generally performed using a combination of two mirrors rotating on perpendicular axes.

ST’s MEMS micromirror solutions combines MEMS micromirrors with the dedicated electronic components to build a complete LBS system. This portfolio includes:
- MEMS micromirrors, either based on single- or dual-axis architecture, for visible or invisible (IR) projection.
- MEMS micromirror driver ICs to ensure the accurate control of mirror positioning.
- A Laser Diode Driver (LDD) specifically developed for Augmented Reality (AR) applications, which require low-power, high-resolution visible projection systems.
