| Abstract(in English) | Numerical simulations were conducted to investigate the ability of a sensing system based on a coherent OTDR with a precisely frequency-controlled light source for measunng realistic temperature distributions that include spatial vanations of several tens of degrees centigrade with steep and gentle gradients It was confirmed that the system allows us tc perform such measurements in a few minutes It was also found that the measurement time may be reduced to less than ten seconds by introducing Barker codes or quasi Barker codes into the system |
