Latest Patents

Chao Sun's latest patents include the "Sparsely-bonded CMOS hybrid imager" and "CMOS imager for pointing and tracking applications." The Sparsely-bonded CMOS hybrid imager patent describes a method and device for imaging or detecting electromagnetic radiation. This device structure features a first chip interconnected with a second chip, where the first chip includes a detector array with multiple light sensors and transistors. The second chip contains a Read Out Integrated Circuit (ROIC) that reads out signals produced by the light sensors. Notably, the number of interconnects between the ROIC and the detector array can be less than one per light sensor or pixel.

The CMOS imager for pointing and tracking applications patent outlines systems and techniques for realizing pointing and tracking applications with CMOS imaging devices. This technique involves sampling multiple rows and columns of an active pixel sensor array into an on-chip memory array. The image data is then read out from the memory array to provide reduced motion artifacts. Various operation modes are available, including TDS, CDS, CQS, and a tracking mode that utilizes a diagonal switch array. This imager device can be integrated into larger imaging systems for both space-based and terrestrial applications.
