| Abstract(in English) | We extended measurand range of a coherent OTDR by introducing a fully tunable DFB laser whose optical frequency can be precisely controlled for measuring distributed strain and temperature with a very high resolution We achieved distributed measurements of temperature that includes spatial vanations of 10℃ with steep gradients over a 10-km long fiber with a resolution of 0 07℃ and a spatial resolution of 20 cm |
