Abstract:
A method of optical sensing is disclosed. The method comprises coupling an excitation optical signal into a first optical fiber to induce Rayleigh backscattering, thereby providing a backscattered signal; coupling the backscattered signal into a second optical fiber, spatially separated from the first optical fiber; and optically amplifying the backscattered signal in the second optical fiber, thereby generating a sensing signal.

Claim (Index 20):
A method of optical sensing, comprising:\n coupling an excitation optical signal into an optical fiber to induce Rayleigh backscattering, thereby providing a backscattered signal; optically amplifying said backscattered signal in said optical fiber, thereby generating a sensing signal; and transmitting said sensing signal into a signal analyzer, for analyzing said sensing signal so as to identify a change in at least one property along said first fiber; wherein said optically amplifying is by pump light beam at intensity I that is satisfying gI\u2265\u2265K+2\u03b1, said \u03b1 being a Rayleigh scattering coefficient characteristic to said fiber, said g being a gain coefficient characteristic to said fiber, and said K being a predetermined variation rate which larger than \u22120.01 m \u22121 .
