High-Definition Sensor

OmniVision Technologies, Santa Clara, CA, has released the latest member of its high definition (HD) medical image sensor family. The OH01A employs the PureCel®-S stacked-die architecture to provide the compact size, high resolution, and cost-effectiveness required for the next generation of disposable and reusable endoscopes and catheters. The sensor is the world“s first medical image sensor to provide 1280 × 800 resolution at a rate of 60 frames per second (FPS) in a tiny 2.5 × 1.5 mm package. These features make it an ideal imaging solution for many diagnostic endoscope procedures, including airway-management (esophagoscopes, laryngoscopes, thorascopes, pleuroscopes, bronchoscopes, mediastinoscopes) and urology (utero-renoscope) applications. Being stereo-ready, two sensors can be synchronized to create 3D images for surgical procedures. Power consumption is 25 percent lower than that of previous-generation medical image sensors, which keeps the distal tip of the endoscope cooler for greater patient comfort. A high chief ray angle of 32° enables a wider field of view in a slimmer module, resulting in a shorter rigid endoscope distal tip that allows for a tight bend radius.
