Abstract |
AB |
[EN] A method and device for detecting the amplitude and/or the phase position of an intensity-modulated signal, including the following: detecting an instant value of the intensity-modulated signal and of a first reference signal with a frequency differing from the intensity-modulated signal; mixing the first reference signal with the intensity-modulated signal to obtain a mixed-signal value; detecting an instant value of a second reference signal with a frequency differing from both the previously detected signals and of a third reference signal of the same frequency but phase-shifted from the second reference signal; mixing the mixed-signal value with the second reference signal to yield a first measurement value; mixing the mixed-signal value with the third reference signal to yield a second measurement signal value; and calculating the amplitude and/or phase position from the two measurement signal values. |
