Abstract

A fiber optic sensor for measuring thickness of transparent plates (1 to 2.5 mm) is proposed based on reflective type displacement fiber optic sensor. The peak position in the output of the receiving fiber, which various linearly, is related to the thickness of the transparent plate. Theoretical model is proposed and compared with the experimental results. The output characteristics of the sensor are studied in terms of fiber optic parameters such as numerical aperture and diameter.
