Abstract
A Brillouin optoelectronic measurement method includes the steps of, providing a pump signal in a first end of an optical fiber to generate Brillouin backscattering, using the generated Brillouin backscattering to perform a measurement, wherein the pump signal includes a front pulse and a rear pulse, wherein the front pulse is modulated.
Claims10
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,
- using the generated Brillouin backscattering to perform a measurement,
- characterised in that 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 such that there is zero amplitude between said at least two pulses, and wherein the rear pulse is non-modulated.
