Omnivision has announced what it claims is the industry’s first and only three-layer stacked BSI global shutter (GS) image sensor. The OG0TB is offered as the world’s smallest image sensor for eye and face tracking in AR/VR/MR and Metaverse consumer devices.
With a package size of just 1.64mm x 1.64mm, the OG0TB has a 2.2µm pixel in a 1/14.46-inch optical format (OF). The CMOS image sensor features 400×400 resolution and ultra-low power consumption, ideal for some of the smallest and lightest battery-powered wearables, such as eye goggles and glasses.
“Omnivision is leading the industry by developing the world’s first three-layer stacked global shutter pixel technology and implementing it in the smallest GS image sensor with uncompromising performance,” says David Shin, staff product marketing manager – IoT/Emerging at Omnivision. “We pack all of these features and functions into the world’s smallest ‘ready-to-go’ image sensor, which provides design flexibility to put the camera in the most ideal placement on some of the smallest and slimmest wearable devices. Ultra-low power consumption is critical for these battery-powered devices, which can have 10 or more cameras per system. Our OG0TB BSI GS image sensor consumes less than 7.2mW at 30 frames per second (fps).”
The OG0TB, says the company, features its most advanced technology:
- It is built on the company’s PureCel®Plus-S stacked-die technology.
- It features a three-layer stacked sensor with pixel size at 2.2µm in a 1/14.46-inch OF to achieve 400×400 resolution.
- Nyxel technology enables the best quantum efficiency (QE) at the 940nm NIR wavelength for sharp, accurate images of moving objects.
- The sensor’s high modulation transfer function (MTF) enables sharper images with greater contrast and more detail, which is especially important for enhancing decision-making processes in machine vision applications.
- The sensor supports a flexible interface, including MIPI with multi-drop, CPHY, SPI, etc.
The OG0TB GS image sensor will be available for sampling in Q3 2022 and in mass production in 2H 2023.
