Euro NCAP standards and European Commission (EC) regulation that mandates the technology from 2022, as well as the U.S. National Transportation Safety Board (NTSB) noticed recommending the use of DMS in semi-autonomous cars.

The VCSEL-supported driver/occupant monitoring systems (DMS/OMS) function as an enhanced kind of in-cabin, near-IR camera, allowing the vehicle to understand the positions, sizes, and actions of the driver and passengers. DMS/OMS is key function in Level-3 automated driving systems.

Comparing IR-LED, VCSELs based illuminator usually give a better uniformity and narrow FWHM which lead to better SNR in both 2D and 3D solution.
