DISPLACEMENT MEASUREMENT TECHNIQUE Russian patent published in 2002 - IPC

Abstract RU 2189111 C2

FIELD: automatic control; conversion of nonelectric quantities to electric signal. SUBSTANCE: proposed technique involves generation of reference signal having known spectrum, determination of outputsignal spectrum, comparison of reference and output-signal spectrums, and evaluation of excitation signal spectrum in case they are not identical taking into account reciprocal Fourier transformation. EFFECT: enhanced measurement accuracy. 1 dwg _
