OMNIVISION’s OGOVA is a low voltage, high performance image sensor with the industry’s smallest pixel size of 2.2 microns. The OGOVA features OMNIVISION’s PureCel®Plus-S stacked pixel architecture and Nyxel® NIR technology to enable optimal performance and precision along with industry-leading QE and excellent MTF for sharp, accurate images in machine vision and 3D sensing applications. This image sensor is an expansion of its backside-illuminated (BSI), global shutter (GS) sensor family that provides VGA resolution options with the best NIR performance in a global shutter device.
The OG0VA image sensor provides 640 x 480 VGA resolution at 240 frames per second (fps) and 320 x 240 QVGA resolution at 480 fps, in the industry’s smallest optical format of 1/10 inches. Additionally, its low light sensitivity is excellent, with significantly lower gain than the industry’s typical 3.0 micron pixel size for an improved signal-to-noise ratio.
The image sensor’s high MTF enables sharper images with greater contrast and more detail, which helps to enhance machine vision decision-making processes. The OGOVA also has a high QE of 40% at 940 nm and 60% at 850 nm. This industry-leading QE enables the device 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, while industrial and robotics applications can use fewer IR LEDs for lower system cost, or use the same number to achieve a greater image detection range.
