Abstract:
A proximity sensor arrangement comprises an optical barrier being placed between a light emitting device and a photo-detector. The light emitting device, the photo-detector and the optical barrier are covered by a cover. The optical barrier is being designed to block light emitted from the light emitting device to the photo-detector and reflected by the cover by means of specular reflection. Furthermore, the optical barrier is being designed to pass the light emitted from the light emitting device to the photo-detector via the cover and scattered on or above a first surface of the cover facing away from the light emitting device and the photo-detector.
