Abstract :
A novel method is proposed to implement a sensor for the measurement of an object size or position. It uses an adjustable-length fluorescent optical fiber and a large luminescent source. A physical model is developed, showing how to combine different measurements in order to reject the influence of possible drifts such as source intensity variations. Experimental results are presented, and good agreement with the theoretical model is obtained. Theoretical and experimental values of the resolution are given. A computer simulation to analyze the influence of the system parameters is reported
