Abstract: Embodiments relate to a proximity sensor, particularly for mobile devices like smartphones, tablets or the like. The proximity detector includes a first emitter-detector pair with a first light emitter and a first photodetector, wherein the first light emitter and the first photodetector are separated by a first distance, and a second emitter-detector pair with a second light emitter and a second photodetector, wherein the second light emitter and the second photodetector are separated by a second distance, wherein the first distance is different from the second distance. Embodiments further relate to a method for detecting the proximity of a target to a proximity sensor.
