Paper Abstract

In order to study the effect of reflector angle on the performance of two fiber distance sensor with single mode illumination, a theoretical model approximating the illumination light exiting the single mode fiber as having a Gaussian intensity profile is established to describe the intensity modulation performance by taking the reflector angle into consideration, and measurements were made to verify the validity of the theoretical model. Numerical simulation results indicate that although the effect of reflector angle α on the sensitivity becomes weaker when α is positive, the blind region, linear range, peak position and sensitivity decreases as the reflector angle becomes more and more positive. The study would help the design and application of fiber distance sensor with single mode illumination.
