Abstract: A spectrometer recognizes a measurement target on the basis of the spectral data set of observed light detected by a spectral sensor capable of measuring wavelength information and light intensity information. The spectrometer is provided with a spectral data processor. Spectral data sets are detected at two different positions by the spectral sensor, and the processor subtracts a first spectral data set from a second spectral data set, or divides the first spectral data set by the second spectral data set to calculate one phase correlation spectral data set, which is correlated to the spectral data sets at the two different positions. The processor simultaneously identifies the measurement target corresponding to the two different positions on the basis of the correlation spectral data set.

Abstract: A method and device for optical teledetection of compounds in a medium includes a detection measurement carried out by emitting into the medium, short pulses of light at least 3 nm wide, and detecting a part of the light back-scattered by the medium by means of a detection unit with temporal resolution. A reference measurement in which the light emitted or the light back-scattered is filtered by virtue of addressable filters, simulating the optical spectrum of the light at the working wavelengths of at least one given compound to be searched for. A comparison of the detection and reference measurements is made to deduce therefrom the possible presence of the compound or compound(s) searched for in the medium. The addressable filters are modified dynamically, and a series of reference measurements and corresponding comparisons are performed for a series of various compounds liable to be present in the medium.
