OmniVision Technologies, a company specializing in image sensors, introduced a new model – OH02A1S. According to OmniVision, it is the world’s first medical image sensor RGB-IR, which provides simultaneous color image acquisition (RGB) in the visible range and monochrome – in the infrared, and will reduce the size, cost, power consumption and heat dissipation of the endoscope by half.
While endoscopic procedures to detect precancerous lesions and cancers are performed using infrared light, surgeons also need to obtain an RGB image to confirm any abnormalities detected by infrared radiation. Previously, this could only be achieved by integrating two independent sensors, which increased the size and cost of endoscopes. In addition, power consumption was increased, resulting in the endoscope tip being overheated. The OH02A1S allows developers to opt out of a second image sensor, eliminating the disadvantages mentioned above.
The OH02A1S uses PureCel architecture with 1.4 µm pixels and 4×4 binning to improve image quality. This architecture provides high quantum efficiency for superior low light performance and wide dynamic range. The image at a resolution of 1920 x 1080 pixels with a frame rate of 60 fps or 1280 x 720 pixels with a frame rate of 90 fps is output via MIPI (two lines). The power consumption is only 90 mW. The 1/6 inch optical sensor is packaged in a 3.8 x 2.9 mm housing.
