Abstract: An imaging system may include a modulation component to provide a modulation signal. The imaging system may include an illumination component to receive the modulation signal and emit a modulated optical signal based on the modulation signal, and provide an electrical illumination signal. The electrical illumination signal may be an electrical representation of the modulated optical signal emitted by the illumination component. The imaging system may include an electrical mixer to receive the electrical illumination signal and the modulation signal, multiply the electrical illumination signal and the modulation signal in order to form a mixed signal, filter the mixed signal in order to form a filtered mixed signal, and output, based on the filtered mixed signal, a calibration signal associated with calibrating the imaging system.
