Paper Abstract

A technique for temperature-insensitive displacement measurement using a single fiber Bragg grating (FBG) based on strain-gradient-induced reflection spectrum bandwidth modulation and optical power detection is demonstrated. Linear displacement measurement up to 20mm with displacement resolution of 0.054 mm and thermal stability of < 0.8 % F.S. for temperature range from 20 °C to 80 °C are respectively achieved without any temperature compensation.i
