Paper Abstract

Historically, nonlinear response and errors introduced by variations in target reflectivity and surface finish have limited the use of fiber optic proximity probes. Recent experimentation with signal processing techniques as applied to these probes has resulted in linearized response over finite displacement ranges and minimization of the effects of variation in target surface. Implementation of these techniques in both analog and digital systems is discussed, and comparisons of the design tradeoffs in each approach are summarized. Experimental data gathered with compensated instruments are contrasted with the performance data from noncompensated devices. Secondary effects introduced by the compensation schemes are defined.
