Image sensor enables smaller sized endoscopes

The OmniVision OH02A1S supplies simultaneous white-light RGB and also IR monochrome capture in a solitary CMOS clinical image sensing unit Making use of the OH02A1S, designers of chip-on-tip endoscopes for cancer discovery can get rid of a 2nd picture sensing unit. The integration of IR and also RGB light in a solitary sensing unit not only decreases the dimension of endoscopes, yet also cuts cost, power, and heat.

Endoscopes equipped with the OH02A1S sensor enable cosmetic surgeons to switch over in between high-grade RGB and also IR in actual time or screen both pictures at the same time overlaid on one display, or side-by-side on two monitors. In addition, the smaller dimension and also decreased warmth of an OH02A1S-enabled endoscope suggests it can get to further right into the body than was previously possible with larger outside-diameter, two-imager styles. Sensor power usage of just 90 mW at full power causes less warm generation.

The OH02A1S utilizes a 1.4-micron PureCel pixel style with 4 × 4 binning for the highest possible picture quality. This style offers high quantum performance for strong low-light performance and also a high vibrant variety for quality in scenes with widely contrasting bright and dark areas. The sensing unit delivers 1080p (1920 × 1080) resolution at 60 frames/s or 720p (1280 × 720) resolution at 90 frames/s through a two-lane MIPI serial outcome. It additionally packs 2 kbits of on-chip one-time-programmable memory.

Used in a 1/6-in. optical layout, the OH02A1S RGB-IR medical picture sensing unit is available now in a 3.8 × 2.9-mm chip-scale plan.
