SeeDevice Announces PAT-PD(TM) Smart Vision Sensor With Quantum Tunneling, Dramatically Improving Imaging Quality

By IQT News posted 19 Aug 2020

(Finance.Yahoo) SeeDevice, a pioneer in quantum image sensing technology, today announced the general licensing availability of Photo Assisted Tunneling – Photo Detector (PAT-PDTM). The agreement allows partners to easily integrate SeeDevice’s smart sensing technology into their products.
“PAT-PD uses quantum tunneling to rewrite a lot of the current specifications for light sensors. placing it in an entirely new category of photon sensing capability,” said Hooman Dastghaib, CEO of SeeDevice.
PAT-PD expands the photosensitive light range of CMOS sensors beyond visible light, into the near infrared (NIR) spectrum (between 300nm-1,600nm) with plans to expand to 2,000nm with their next-generation sensor, enabling shortwave infrared (SWIR) frequencies to maintain high visual quality sensing in low-light and near no-light use cases.
Additionally, the PAT-PD sensor increases photo-sensitivity to 106 A/W, while maintaining a Signal to Noise Ratio (SNR) of over 60dB at room temperature, delivering an image signal that is consistently sharp and crisp.
Reaction time is also reduced from microseconds to sub-nanoseconds while boosting dynamic range to 100dB linear and 150dB non-linear, allowing the PAT-PD sensor to capture images in record time while maintaining an extremely high-fidelity image.
SeeDevice achieves these results using standard CMOS fabrication process allowing for easy integration in mixed-signal process and avoiding expensive exotic materials and manufacturing processes to achieve similar results.
