Abstract (en)
[origin: WO2008152286A2] The invention relates to a method of optical teledetection of compounds in a medium in which: - a detection measurement is carried out by emitting into the medium, short pulses of light at least 3 nm wide, and detecting a part of the light backscattered by the medium by means of a detection unit with temporal resolution, - a reference measurement in which the light emitted or the light backscattered is filtered by virtue of addressable filtering means, simulating the optical spectrum of the light at the working wavelengths of at least one given compound to be searched for, - a comparison of a detection measurement and of a reference measurement, so as to deduce therefrom the possible presence of the compound or compounds searched for in the medium, - the addressable filtering means are modified dynamically, and a series of reference measurements and a series of corresponding comparisons are performed for a series of various compounds liable to be present in the medium, as well as a device adapted for implementing such a method.
