摘要：
A fiber optic sensor for determining the thickness of a transparent plate (1-2.5 mm) is described based on a fiber optic displacement sensor. The sensor characteristics are found to vary with the change in the thickness of a plate. A theoretical model is proposed and validated with experimental results. The behavior of the sensor is evaluated and analyzed in terms of the numerical aperture and diameter of the fiber. (C) 2010 Elsevier Ltd. All rights reserved.
