OmniVision quadruples resolution and downsizes the world’s smallest commercial image sensor

OmniVision Technologies announced the OH0TA OVMed medical imaging sensor. The body size of this sensor is only 0.55mm x 0.55mm and the optical format is 1/31 inch. This is smaller than the OV6948, which is listed in the Guinness Book of World Records as “the smallest commercially available image sensor.”

RGB resolution is quadrupled from OV6948. It is 400 x 400 pixels. Like its predecessor, the new sensor can form an image at 30 fps, but the power consumption has been reduced by 20% – to 20 mW. This allows designers to add ultra-compact imaging to disposable and reusable endoscopes, as well as catheters and guidewires with a small outer diameter of only 1 to 2 mm. Alternatively, the uniquely small size of this sensor gives medical device manufacturers the ability to create larger diameter devices with a large working channel.

The OV6948 has a pixel size of 1.0 μm. The sensor uses a proprietary multilayer PureCel Plus-S technology. It delivers high color accuracy and low light sensitivity of 3600 mV / lx s and a high signal-to-noise ratio of 37.5 dB. The sensor supports a 4-wire interface as well as raw analog data output. In both cases, the cable length can be up to 4 m. Ease of use is provided by the ability to interface with the OmniVision OV426 ADC microcircuit. In addition, the probe is autoclavable, making it suitable for reusable endoscopes.

OH0TA samples are already available.
