Abstract
Aspects of the disclosure pertain to a system and method for reducing ambient light sensitivity of Infrared (IR) detectors. Optical filter(s) (e.g., absorption filter(s), interference filter(s)) placed over a sensor of the IR detector (e.g., gesture sensor) absorb or reflect visible light, while passing specific IR wavelengths, for promoting the reduced ambient light sensitivity of the IR detector.
