Realisation of an effective dual-parameter sensor employing a single fibre Bragg grating structure

摘要

A novel technology for simultaneous and independent measurement of dual parameters is proposed and experimented. The length of a single fibre Bragg grating (FBG) is divided into two parts. The temperature variation and another measurand can be measured independently and simultaneously, and the thermal effect can be erased with great ease. (C) 2005 Elsevier Ltd. All rights reserved.
