| Abstract: | We present an improved scheme of distributed fiber temperature sensors. Usually, Stokes and anti Stokes are obtained in the same port of a coupler by splitter. In the scheme, they are obtained in different ports of the coupler with no influence each other. The anti Stokes obtained in the scheme is larger than that in usual scheme. It is of great importance to distributed fiber temperature sensors. |
