  • Patent number: 10761197
    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.

  • Publication number: 20200271765
    Abstract: A method is presented for calibrating a time-of-flight system having a time-of-flight sensor located behind a cover plate. The method involves emitting a plurality of sending pulses of light in response to respective trigger pulses of a control signal and detecting received pulses of light. Respective difference values are determined which are representative of a time period between one of the sending pulses and one of the received pulses. The difference values are accumulated into a number of bins of at least one histogram. The method further involves recording at least one crosstalk response in the histogram within a predetermined range of bins, and calibrating the histogram using the recorded crosstalk response. Finally, an output signal is generated which is indicative of a time-of-flight based on an evaluation of the calibrated histogram.

  • Patent number: 10732576
    Abstract: A time-to-digital converter system has at least one time-to-digital converter comprising an oscillator, a counter being driven by the oscillator, an evaluation block connected to the counter and configured for determining a time difference associated with a start signal and a stop signal, and a histogram block with a number of bins for recording entries associated with the time difference. The system can be calibrated by operating or preparing to operate the time-to-digital converter system with a measurement clock signal defining a measurement interval, providing a calibration clock signal having a frequency higher than the measurement clock signal by a predefined ratio, using a selected clock edge of the calibration clock signal as the start signal and a subsequent clock edge of the calibration clock signal as the stop signal. The evaluation block determines a calibration time difference based on the respective clock edges of the calibration clock signal used as the start signal and the stop signal.

  • Patent number: 10190905
    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.

  • Patent number: 9528820
    Abstract: An optical proximity sensor often emits light, and detects the photons in the returned light signal. Because light can be reflected and scattered by cover glass and ink layer printed on the cover glass, optical crosstalk is a concern for the optical proximity sensors. In one embodiment, the present disclosure provides an optical proximity sensor including a linear polarizer to cover the photo detector, or a polarizer to cover the light emitting device, or two polarizers to cover both the photo detector and the light emitting device. The polarizer blocks the s-polarized light and only allows the p-polarized light to pass through. Because the scattered light is predominated by the s-polarization, the optical crosstalk may be reduced.
