Displacement Sensing with Polymer Fibre Optic Probe
並列摘要
The principle of operation, design aspects, experimentation and performance of a polymer fibre optic probe for sensing micro displacement are discussed. The device is based upon the phenomenon of reflective concept. The sensor can work in either the positive slope region or the negative slope region, in addition, it is capable to measure displacement ranging from 0.1 to 0.8 mm with sensitivity of 2.619 V/mm in the positive slope region and 1.3 to 2.9 mm in the negative slope region with a sensitivity of -0.814 V/mm. The simplicity of design, high precision, stability, linearity, high degree of sensitivity, dynamic range, non-contact sensing and low cost of the fabrication make it suitable for real field applications.
