OmniVision says it has the smallest-ever pixel size of 2.2 microns for a backside-illuminated (BSI), a global shutter image sensor. Its OG01A sensor joins PureCel Plus-S pixel technology and Nyxel near-infrared (NIR) technology to allow optimum performance and precision with NIR quantum efficiency (QE).
This sensor is appropriate for a variety of consumer and industrial purposes that want a global shutter to avoid motion blur, along with prime NIR performance for low- and no-light situations.
The OG01A is well-suited to several machine-vision functions, including AR/VR headsets, drones, robots, and simultaneous localization and mapping, in addition to facial authentication in smartphones and other consumer devices.
This know-how is also appropriate for automotive in-cabin driver state monitoring and eye monitoring.
The 1-megapixel OG01A image sensor gives 1280×1024 resolution at 120 frames per second and 640×480 resolution at 240 frames per second in a compact 1/5 inch optical form. High shutter performance allows for cleaner motion capture and a high dynamic range. The sensor’s low-light working ability has lower gain than the usual 3.0-micron pixel size for an improved sign-to-noise ratio.
The sensor’s high Modulation Transfer Function (MTF) permits sharper pictures with better contrast and additional details, which is particularly important for enhancing resolution-making processes in machine imaginative and prescient purposes.
The OG01A additionally has a QE of 40% at 940nm, and 60% at 850nm which allows the sensor to see farther and higher in low- and no-gentle situations, which permits designers to use much less IR LED light and obtain decrease system-stage energy consumption.
For AR/VR headsets, this reduces warmth technology. For industrial and robotics functions, designers can use fewer IR LEDs for lower system price or use the same variety of IR LEDs to realize a greater picture detection range.
