Claim Text:
1. A Brillouin optoelectronic measurement method comprising the steps of: providing a pump signal in a first end of an optical fiber to generate Brillouin backscattering; and using the generated Brillouin backscattering to perform a measurement, wherein the Brillouin backscattering generated is associated with a portion of an incident power of the pump signal that is propagated back to the first end of the optical fiber, wherein the pump signal comprises a front pulse and a rear pulse, wherein the front pulse is amplitude modulated such that the front pulse defines at least two pulses and there is zero amplitude in the interval between said at least two pulses, and wherein the rear pulse is non-modulated, wherein the front pulse is provided into the optical fiber before the rear pulse.
