Abstract:
A distributed device for the detection of a substance is disclosed, comprising: a distributed optical excitation source ( 21 ) including a first optical fiber ( 22 ) having a plurality of extraction regions ( 24 ), each extraction region ( 24 ) being adapted to extract part of the light carried by the first optical fiber ( 22 ) from said fiber; and a distributed acoustic sensor ( 25 ) including a second optical fiber ( 26 ).

Claim (Index 1):
A distributed substance detection device, comprising:\n a distributed optical excitation source comprising: a first optical fiber provided with a plurality of extraction regions, each extraction region being capable of extracting from the first optical fiber part of the light conveyed by the fiber; a first light source capable of injecting into the first optical fiber a first light signal at an absorption wavelength of the substance to be detected; and a control circuit capable of modulating the first light signal in intensity at an acoustic frequency; and a distributed acoustic detector comprising: a second optical fiber; a second light source capable of injecting a second light signal into the second optical fiber; and an optical detector capable of measuring a third backscattered light signal in the second optical fiber to detect and locate an acoustic vibration at the modulation frequency of the first light signal.
