Abstract
An apparatus includes a detector circuit configured to receive a modulated electromagnetic wave signal from an illumination source and to provide a detection signal having a frequency dependent on a modulation frequency of the modulated electromagnetic wave signal. The apparatus further includes a reference circuit configured to generate a reference signal based on the detection signal. The apparatus further includes a sensor circuit configured to generate based on the reference signal a sensor signal based on reflected modulated electromagnetic waves emitted by the illumination source and reflected by an object. The apparatus further includes a processing circuit configured to determine distance information related to the object based on the sensor signal.
