A demodulation system and algorithm of FBG sensor based on DSP

Wavelength interrogation technology is the key technology of optical fiber sensors.A FBG sensor demodulation system is introduced based on tunable fiber F-P filter and DSP chip.A fast,stable and high resolution demodulation algorithm is demonstrated.Wavelength resolution of 2pm and wavelength measure range of 50nm are achieved.The DSP chip is used to control the optical scanning system,datum acquisition and processing.The demodulation speed of the system is improved.

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
