System and method for reducing stray light interference in optical systems

Abstract

Disclosed herein are systems, methods, and computer program products for reducing optical interference in an optical sensor. The methods comprise: detecting, by an optical sensor device comprising a plurality of pixel sensors, a signal with a reflected light component and a stray light component; estimating, by a processor, a stray light intensity in each pixel of the plurality of pixel sensors using a measured mapping of an intensity of stray light relative to an intensity of reflected light, wherein the measured mapping is derived from the measured intensities associated with all pixel sensors of the optical sensor device; adjusting, by the processor, a noise probability for the signal using the estimated stray light intensity and an unbiased noise intensity; and adjusting, by the processor, a signal confidence score using the adjusted noise probability.
