Abstracts

EN

Modelling and experimental investigation of U-h characteristics of fiber-optic reflective displacement transducer, with the aim to obtain the maximal sensitivity and high speed in the displacement and vibration measurements, are presented. Excellent agreement between theory and experiment was obtained, therefore the limiting sensitivity of transducers can be predicted by modelling. Configurations of non-contact fiber optical transducers of the maximal possible sensitivity and speed were found, the metrological parameters which do not depend either on the degradation of the light source intensity or on elements used in the measurements, as well as on the value of the mirror reflection coefficient and changes due to aging. All that increases the reliability of measurement system, which is of utmost importance for process monitoring.
