Static Fiber-Bragg Grating Strain Sensing Using Frequency-Locked Lasers

Not Accessible

Your library or personal account may give you access

Abstract

Novel and highly sensitive static strain interrogation technique is demonstrated, where the sensing element is a fiber-Bragg grating (FBG) and the light source is a frequency-locked diode laser. Locking the laser frequency to the center of an absorption line (atomic line of potassium in our experiment) eliminates the slow frequency drift of the laser. The stabilized laser source is used to measure low frequency ("static") strain, with a sensitivity of 1.2 nanostrain/{\sqrt Hz } rms at 1.5 Hz.
