摘要
Aspects of the present disclosure describe Raman based Distributed temperature sensing (DTS) systems with a novel recovery algorithm that improves the spatial resolution of DTS system. The algorithm is based on a linear DTS model and weighted total variation. Furthermore, we describe an additional algorithm which can automatically detect and recover any hot regions along the fiber—with the recovery algorithm as its core—achieving correct reconstruction with a temperature profile down to 10 cm in length—which is equivalent to improving the spatial resolution to about 5 cm
