Abstract: A method for gesture detection comprises pre-processing and main-processing steps, wherein the pre-processing comprises emitting light using a light emitting device and generating of directional sensor signals as a function of time by detecting a fraction of the emitted light reflected by means of a movable object using a directional light sensor array). The main-processing comprises calculating coordinates as a function of time by using the directional sensor signals, being indicative of a position of the object with reference to a plane parallel to a principal plane of the light sensor array, and detecting a movement of the object depending on the timing of the coordinates.

Abstract: A light sensor arrangement comprising a stack having a light sensor, an optical filter, and a mask between the light sensor and the optical filter. In particular, the light sensor comprises a light sensitive surface. The mask comprises an upper opaque base facing away from the light sensitive surface and having first apertures each confining an optical path in the mask, respectively. The mask further comprises a lower opaque base facing the light sensitive surface and having second apertures, each confining the optical path in the mask, respectively. The upper and lower base are made from metal. The optical paths are designed for allowing incident light to reach the light sensitive surface when having an angle of incidence from an allowed interval of angles determined by the size of the first and second apertures and defined with respect to an optical axis of the optical paths, respectively. A spectrometer is shown comprising at least light sensor arrangements of the aforementioned kind.

Abstract: An optical sensor module for time-of-flight measurement comprises an optical emitter, a main detector and a reference detector which are arranged in or on a carrier. An opaque housing of the optical sensor module has a first chamber and a second chamber which are separated by a light barrier. The housing has a cover section and is arranged on the carrier such that the optical emitter is located inside the first chamber, the main detector is located inside the second chamber and the reference detector is located outside the first chamber. Furthermore, a main surface of the cover section is positioned opposite the carrier. The optical emitter is arranged and configured to emit light through a first aperture in the cover section, and the main detector is arranged and configured to detect light entering the second chamber through a second aperture in the cover section. A reference path is established between the optical emitter and the reference detector inside the optical sensor module, and confined by the main surface of the cover section and the carrier. Additionally, a method for manufacturing an optical sensor module for time-of-flight measurement is presented.
