Brillouin Optical Time Domain Analyzer Fiber Sensor Based on FPGA Accelerated Support Vector Regression

Support vector regression and its FPGA implementation have been employed in a BOTDA system to extract temperature information. Post-processing of 96,100 BOTDA data points along 38.44-km fiber can be completed within 0.5 seconds.
