These features of the OH01A make it an ideal image solution for many diagnostic endoscopic procedures, including airway management (esophageoscopy, laryngoscopy, thoracoscopy, pleural mirrors, bronchoscopy, mediastinoscopy) and urology (intrauterine kidney Mirror) applications etc.
'Because catheters need to enter the human body for diagnosis, doctors need smaller, higher resolution and best image quality image sensors.' Tehzeeb Gunja, chief marketing development manager at OmniVision said, 'At the same time, they also need a broad vision. Angle and near-focus distance, as well as low power consumption to reduce heat, improve patient comfort. OH01A image sensor meets all the above requirements.
The OH01A has 1/11-inch optical dimensions, 1.1 micron pixels and raw data output. It offers 1280 x 800 resolution, and can also be adjusted to 720p HD display (16:9 aspect ratio) or 800 x 800 square display. The modes are running at a frame rate of 60 per second, and the images are crisp and jitter-free. The sensor's PureCel-S stacked pixel architecture provides the highest quality images while improving sensitivity, full well volume, no halos, and low color crosstalk.
The OH01A image sensor is also suitable for stereoscopic display applications. The two OH01A can be simultaneously operated to provide 3D images for the surgical process. The power consumption is also reduced by 25% compared with the previous generation medical image sensor, making the endoscope tip temperature lower and making the patient more comfortable. In a small module, a 32-degree high chief ray angle provides a wider visual range, making it possible to use a shorter rigid endoscope tip to make the bending radius closer.
The OH01A supports MIPI and the secondary-LVDS output interface for long-distance transmission of image data. It also integrates one-time programmable (OTP) memory for storing production and calibration information.
OH01A can be used for high-pressure treatment of circulating equipment and disinfection of disposable equipment.
OH01A is now available for sampling and is expected to be in volume production in the fourth quarter of 2018.
