OH02A1S (the sensor for endoscopes)

2020: The announcement of OH02A1S - the sensor for endoscopes

At the end of September, 2020 the OmniVision Technologies company provided OH02A1S, the first-ever medical RGB-IR sensor for endoscopes which uses both normal light (RGB), and infrared (IR). Developers claim that this sensor is less by the sizes, is cheaper and more powerful than analogs.

Endoscopic procedures of detection of a precancer and cancer are executed using infrared light, but normal light is also necessary for surgeons for confirmation of any deviations. Before it it was possible to reach only by integration of two independent sensors that inevitably increased the sizes, the cost and energy consumption of endoscopes and also to excessive heating of its tip. Developers note that OH02A1S allows to refuse the second sensor and by that gets rid of shortcomings of construction of the endoscope with two thermal imagers. These improvements will allow and to develop further special endoscopes with a small outer diameter for diagnosis of cancer.

OmniVision OH02A1S provides both infrared, and normal images using one chip that allows the surgeon to switch between high-quality RGB-and IK-illumination in real time or to consider both images along with imposing or without it. Besides, the smaller size and the lowered heat release allow the endoscope to get much more deeply, than it was possible earlier. Besides, developers can use the released space for auxiliary illumination or for carrying out endoscopic tools.

OH02A1S has pixel architecture of PureCel of 1.4 microns that provides the high definition of the image even at weak lighting and in the presence of strongly contrasting bright and dark areas. The sensor can provide permission 1080p (1920x1080) at 60 frames per second or 720p (1280x720) at 90 frames per second.^[1]
