Strain sensing using a fiber-optic Bragg grating

摘要: This paper reports on the development of a passive, fast demodulation system for use with in-fiber Bragg gratings used strain or temperature measurements. compact, potentially inexpensive self-referencing permits absolute strain/temperature measurements over wide dynamic range temporal response by tracking wavelength shifts narrow-band back-reflected spectrum. The wavelength, bandwidth and sensitivity sensor are discussed, examples both static shown.© (1991) COPYRIGHT SPIE--The International Society Optical Engineering.
