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.

A light sensor arrangement according to the proposed principle comprises at least one first unshielded well (D) and at least one second shielded well (D) in a substrate (P). The at least one first unshielded well (D) is being exposed to incident light (&#x3bb;) and configured to generate a first sensor signal (Ch) as a function of the incident light (&#x3bb;). The at least one second shielded well (D) in the substrate (p) being shielded from the incident light (&#x3bb;) and configured to generate a second sensor signal (Ch) as a function of the incident light (&#x3bb;). The light sensor arrangement further comprises means for temperature compensation providing the first and second sensor signals (Ch, Ch) as temperature compensated sensor signals as a function of substrate temperature. Means to determine spectral content of the incident light (&#x3bb;) are provided to determine the spectral content as a function of the temperature compensated first and second sensor signals (Ch, Ch).

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.

A photodiode () and a further photodiode () are arranged in a substrate () at or near a main surface (). The photodiodes are formed and arranged in such a manner that in case of incident ultraviolet radiation () the electric signal from the photodiode () is larger than the further electric signal from the further photodiode (). In particular, the first photodiode may be more sensitive to ultraviolet radiation than the further photodiode. The electric signal from the photodiode is attenuated by the further electric signal and thus yields an electric signal primarily measuring the incident ultraviolet radiation. The attenuation of the electric signal from the first photodiode may be achieved internally using an integrated circuit () or externally using a separate device.
