Abstract: The invention relates to a method and to apparatus for remotely measuring the distribution of a physico-chemical parameter in a medium. The method consists in exciting measurement points (20) situated in a medium (17) in succession via an optical fiber (18), with each point (20) being excited by two light pulses of different wavelengths offset from each other in time occurring simultaneously at said point, each measurement point returning radiation at a third wavelength representative of the temperature of the measurement point. The apparatus includes two lasers (3, 4) emitting different wavelengths, a delay circuit (5) for delaying the light pulse from one (4) of the two lasers, and the measurement points include a material sensitive to biphotonic excitation.

Abstract: The optical fibre 5 includes, from the centre to the periphery, a first core 10, a first cladding 11, a second core 12 and a second cladding 13. The device includes a laser whose radiation is transmitted to the body via the first core 10, the radiation scattered by the body being transmitted to an analysis device via the second core 12 of the fibre 5. Application to the remote metering of a mixture of liquids.
