摘要： A method and an apparatus for carrying out a chemical-physical analysis, such as a spectroscopic analysis, an absorption analysis, a scattering analysis, etc. on one or more regions of a sample (11 ), provides prearranging a source (1 ) of a first electromagnetic radiation comprising a plurality of components with respective wavelength, prearranging a plurality of sites (9) distributed on a determined surface to emit the first radiation, arranging such surface facing a corresponding region of a sample (11 ) such that the whole surface thereof is attained by the first radiation, emitting the first radiation on the sample (11) thus causing the emission of a second radiation by the sample (11 ), which is analysed to associate an intensity of the second radiation to each region and wavelength. For each of the wavelength of the first radiation, a wavelength code is selected by which respective components of the first radiation are coded; the coded components are joined together to form the first electromagnetic radiation which is distributed in a plurality of radiation beams. Such beams are conveyed to respective emission sites (9), for each of which an emission site (9) code is selected, a radiation beam being codified by said code. A decoding of the of the second radiation produces a plurality of fractions, each fraction associated to a wavelength of the first radiation such that for each emission site (9) it is possible to instantaneously compare each fraction associated to a respective wavelength with a component of the first radiation having the same wavelength, the components of the first electromagnetic radiation being emitted simultaneously. The steps of wavelength coding and of site coding, and possibly also other coding steps may be earned out subsequently with respect to one another, or at the same time. The method and the apparatus allow reducing the time required to carry out said analysis.
