摘要：

A simple technique to discriminate the Strain and Temperature with a single Fiber Bragg Grating (FBG) at cryogenic regime is presented in this paper. An uniform FBG is divided into two parts, one half is without coating (FBG1) and other half is coated with Cyno-Acrylic Adhesive (FBG2). The measured temperature and strain sensitivities of the FBG 1 are 4.05x10-6/K and 2.13x10-6/mu epsilon and FBG2 are 1.39x10-5/K and 1.72x10-6/mu epsilon respectively.
