Abstract: An optical sensor arrangement comprises an optical barrier which is placed between a light-emitting device and a photodetector. Herein the light-emitting device and the photodetector are arranged on a first plane and are covered by a cover. The photodetector exhibits an active zone. The optical barrier exhibits an extent along a first principal axis, which is pointing parallel to the line connecting the centers of the light-emitting device and the photodetector. Herein the extent is greater than a dimension of the active zone. The optical barrier is designed to block light emitted by the light-emitting device that otherwise would be reflected by the cover by means of specular reflection and would reach the photodetector. The optical barrier is designed to pass light emitted by the light-emitting device and scattered on or above an outer surface of the cover.

Abstract: A method for passive optical motion detection uses an optical sensor arrangement comprising an optical sensor having at least one signal channel. The optical sensor arrangement is initialized for repeated signal acquisition and an initial frame comprising a tuple of sensor data is collected from the at least one signal channel. The initial frame is set as a previous frame. A loop of motion detection is entered and the following steps are repeated. First, a current frame comprising another tuple of sensor data is collected from the at least one signal channel. Then, a motion parameter is computed from a motion metric depending on the current and previous frames. The so computed motion parameter is compared with a threshold value. A motion event parameter is set depending on the comparison of the motion parameter with the threshold value. The current frame is set as previous frame so that the loop can start all over again.
