The platform incorporates two OmniVision OH02A CMOS image sensors with 1.4-micron pixel PureCel technology in a 1/6-inch optical format and an image signal processor (ISP) from OmniVision, plus a light control board for LED illumination and camera control unit from Lighthouse.
“Traditional endoscopy uses a single camera and does not provide depth information, thus increasing risks during endoscopic surgery,” said Tehzeeb Gunja, principal marketing manager at OmniVision.
“This partnership with Lighthouse Imaging provides an end-to-end, turnkey solution for stereoscopic 3D imaging in applications such as laparoscopy, gastro-intestinal (GI) and general endoscopic surgery. OmniVision’s high-image-quality, high-resolution image sensors, combined with Lighthouse’s system-level integration expertise, allows us to overcome the complexity, cost and size constraints that have limited the wide adoption of 3D endoscopy.”
The sensors support alternate-row high dynamic range (HDR) for high-quality imaging of both bright and dark areas. They are also stereo-ready, with FrameSync technology that enables accurate synchronization of the sensors. On-chip pulse width modulation enables the sensors to drive the LEDs at the endoscope’s distal tip, while antireflective coating on the cover glass removes ghosting. These sensors come in compact chip-scale packages (CSPs) with two-lane MIPI output, and have low power consumption for low heat at the distal tip.
