Abstract
The invention relates to a method for detecting and processing the amplitude and phase of signal waves. A Modulated signal source generates the signal waves which are modified by transmission medium or by reflection and scattering by at least one object. The modified signal waves are received and demodulated using a modulation signal. The amplitude of the modulated signal waves and their phase relationship to the modulation signal are measured and evaluated. The demodulated signal wave is converted into an electrical charge or charge displacement in the receiving medium and is distributed in accordance with a modulation signal to at least two readout outputs and fed to an evaluation unit. The evaluation unit produces the sum and difference of the output signals thus applying the value of the intensity and the phase position of the signal wave that has been scattered, reflected or delayed by the object.
