OH02A1S 1080p product brief

Medical RGB-IR Image Sensor Reduces Endoscope Size,

Cost, Power and Heat by Half

a lead-free

package

OmniVision’s OH02A1S is the world’s first RGB-IR medical image

sensor, providing simultaneous white-light RGB captures and

infrared monochrome captures in a single CMOS sensor for

cancer diagnosis and treatment. While endoscopic precancer and

cancer detection procedures are performed using IR light,

surgeons also need RGB light to confirm any abnormalities

detected using infrared. Previously, this could only be

accomplished by integrating two independent imager sensors,

which resulted in endoscopes with a larger size, higher cost and

higher power consumption, thereby excessively heating the tip of

the endoscope.

With the OH02A1S, both IR and RGB images can now be captured

using a single chip, allowing the surgeon to switch between high

quality RGB and IR in real time, or to display both images

simultaneously on one (overlay) or two (side-by-side) monitors.

Additionally, the smaller size and reduced heat 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 to add

more or larger illumination (fiber or LED), or a larger working

channel for endoscopic tools.

The OH02A1S image sensor is available today in an RW package

and the chip-scale package will be available based on project

demand.

Built on OmniVision’s PureCel® pixel architecture, the OH02A1S

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. The sensor can provide 1080p (1920x1080)

resolution at 60 frames per second (fps) or 720p (1280x720) at

90 fps, via a 2-lane MIPI serial output. The OH02A1S also

integrates 2 kilobits of one-time programmable memory on-chip.

It consumes just 90 milliwatts at full power, generating less heat

for greater patient comfort.
