Omnivision Technologies Inc. (Santa Clara, Calif.) has launched what it claims is the world’s smallest image sensor for eye and face tracking in AR/VR/MR and metaverse consumer devices.

The global shutter OG0TB has a package size of 1.64mm by 1.64mm and a 2.2-micron pixel in a 1/14.46-inch optical format (OF).

The CMOS image sensor features 400 by 400 pixel resolution and low power consumption making it suitable for battery-powered wearables, such as eye goggles and glasses. The OG0TB BSI GS image sensor consumes less than 7.2mW at 30 frames per second.

The market for AR/VR headsets grew 92.1 percent year over year in 2021, with shipments reaching 11.2 million units, according to Omnivision, which referenced market research firm International Data Corporation. Headset shipments are forecast to grow 46.9 percent year over year in 2022.

The sensor is built on the PureCel Plus-S stacked-die technology and has multiple interfaces, including MIPI with multi-drop, CPHY and SPI.

The OG0TB GS image sensor will be available for sampling in 3Q22 and in mass production in the 2H23.
