【Abstract】 At present, the distributed optical fiber sensors have more and more important effect in temperature measurement, structure health monitoring and fault diagnosis for communication optical cable. The distributed optical fiber sensors have many types. Different kind of distributed optical fiber sensor has different measuring theory, measuring accuracy, and measurement range, etc. This paper introduces nine commonly-used distributed optical fiber sensors, and gives some parameters of commercial instruments based on those distributed optical fiber sensors, and finally compares their merits and demerits.更多还原
