    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 sensor arrangement for determining time-of-flight comprises an emitter configured to periodically emit pulses of electromagnetic radiation depending on a first clock signal, a photonic demodulator configured to detect electromagnetic radiation during detection intervals comprising first and second intervals and a processing circuit. A timing of the detection intervals is defined by a second clock signal having a phase difference with respect to the first clock signal. The demodulator is configured to generate demodulator signals depending on energy of the radiation detected during at least one of the first intervals and at least one of the second intervals, respectively. The processing circuit is configured to adapt the phase difference based on the demodulator signals and to generate an output signal indicative of the time-of-flight based on the phase difference.

    Abstract: An optical driver arrangement (10) comprises a comparator (11) and a pulse generator (15). The comparator (11) comprises a first input (12) for receiving a sensed output signal (S1) derived from a sensor signal (S2) generated by a light sensor (24), a second input (13) for receiving a reference signal (S3) and a comparator output (14) for providing a comparator signal (S4). The pulse generator (15) comprises a control input (16) coupled to the comparator output (14) and a generator output (22) for providing a driver signal (S5) to a light source (21). The driver signal (S4) comprises a series of at least one pulse and a parameter of the driver signal (S4) is controlled by the comparator signal (S4).
