摘要：
Cryogenic temperature sensing has been demonstrated using Polymer coated Fiber Bragg Grating Sensor, and the experimental results are presented in this article. Teflon coating thicknesses of 20 and 40 l applied on Fiber Bragg Gratings, inscribed in silica fiber (TFBG) are used for these studies. It was observed that the sensitivity of Teflon-coated FBG has been enhanced three times compared to uncoated regular FBGs. (C) 2011 Wiley Periodicals, Inc.
