Orthogonal code readout (OCR) is a technique to expand machine vision and also simplifies thermal array readout.
An Orthogonal Code Readout (OCR) electronically expands the dynamic range of CMOS active pixels. When OCR is implemented, the dynamic range of a pixel is not limited by per-pixel capacitance. When employed as a thermal array readout, OCR simplifies thermal detector array fabrication by eliminating the need for large electron well capacitors.
