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.
