The OH02A1S from OmniVision Technologies is a CMOS Image Sensor that provides simultaneous white-light RGB captures, and infrared monochrome captures in a single CMOS sensor for cancer diagnosis and treatment. The sensor can provide 1080p (1920 x 1080) resolution at 60 frames per second (fps) or 720p (1280 x 720) at 90 fps, via a 2-lane MIPI serial output. It has a pixel size of 1.4 µm x 1.4 µm and supports a 10-bit RAW RGB-Ir output format. This sensor also integrates 2 kilobits of one-time programmable memory on-chip and consumes 90 milliwatts at full power, generating less heat for greater patient comfort. It is built on OmniVision’s PureCel pixel architecture that offers 4x4 binning for the highest image quality, high quantum efficiency for excellent low-light performance, and a high dynamic range for clarity in scenes with widely contrasting bright and dark areas.
This CMOS sensor can capture both IR and RGB, allowing the surgeon to switch between high-quality RGB and IR in real-time, and to display both images simultaneously on one (overlay) or two (side-by-side) monitors. The smaller size and less heat produced of this sensor allow the endoscope to reach much farther into the body than was previously possible with larger-outer-diameter, two-imager designs. Alternatively, designers can use the extra space feature to add more or larger illumination (fiber or LED), or a larger working channel for endoscopic tools.
This CMOS sensor is available as a die that measures 3875 x 2939 µm and is ideal for applications such as medical endoscopes, veterinarian endoscopes, dental equipment, and industrial endoscopes.
