    Abstract: A method for generating a carrier frequency-modulated signal for the evaluation of n>2 photoelectric measurement signals which are generated by imaging a structured surface onto a spatial frequency filter and are phase-shifted with respect to one another is distinguished by the fact that the amplitudes of the measurement signals are serially interrogated in a predetermined interrogation cycle with a constant clock rate, and a sinusoidal signal is formed by filtering from the signal train, the carrier frequency of which signal is determined by the time for an interrogation cycle.
