Overview

OmniVision's OG01A is a backside-illuminated (BSI) global shutter (GS) image sensor with a pixel size of 2.2 microns. It combines OmniVision's PureCel®Plus-S pixel technology and Nyxel® near-infrared (NIR) technology to enable optimal performance and precision along with industry-leading NIR quantum efficiency (QE). These features make the OG01A ideal for a wide range of consumer and industrial applications that need a global shutter to avoid motion blur, along with top NIR performance for low- and no-light conditions.

The OG01A is well-suited to multiple machine-vision applications, including AR/VR headsets, drones, robots, and simultaneous localization and mapping (SLAM), as well as facial authentication in smartphones and other consumer electronics. This technology is also ideal for automotive in-cabin driver state monitoring and eye tracking.

The 1.3 megapixel OG01A image sensor provides 1280 x 1024 resolution at 120 frames per second (fps) and 640 x 480 resolution at 240 fps in a compact 1/5 inch optical format.

The sensor's high modulation transfer function (MTF) enables sharper images with more detail, which is especially important for enhancing decision-making processes in machine vision applications. The OG01A also has a high NIR QE at 940 nm and 850 nm, enabling the sensor to see farther and better in low- and no-light conditions, which allows designers to use less IR LED light and achieve lower system-level power consumption. For AR/VR headsets, this reduces heat generation. For industrial and robotics applications, designers can use fewer IR LEDs for lower system cost, or use the same number of IR LEDs to achieve a greater image detection range.
