It is based on Pound-Drever-Hall (PDH) laser frequency locking, using radio-frequency phase modulation sidebands to derive an errorKeywords: Fabry-Perot interferometers; Fiber optic sensors; Optical resonators; Phase modulation; Bragg grating interrogation; Bragg grating resonator; Fiber resonator; Frequency locking; Nanostrain; Picostrain; Strain sensor; Fiber Bragg gratings Bragg grating interrogation; Bragg grating resonator; Fiber Fabry-Pérot (FFP); Fiber resonator; Fiber sensor; Frequency locking; Nanostrain; Picostrain; Strain sensor200510.1109/JLT.2005.8468952015-12-12
