Distributed optical fiber sensor using Sagnac for acoustic detection
A distributed optical fiber acoustic sensor based on in-line Sagnac is presented.After clockwise and counterclockwise light waves are recombined,interference in 3×3 coupler is produced.The acoustic sensor uses photo detector(PD),data acquisition card,filter and amplification to realize photo electri...
