摘要：

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 degrees C to 80 degrees C are respectively achieved without any temperature compensation.
