Abstract: Disclosed is a method for acquiring and forming a spectrometry image, including the following steps: a) acquiring an initial structural image of an area of a sample; b) breaking down the initial structural image so as to determine a multi-scale spatial sample of the area of the sample; c) determining a plurality of spectrometry measurement positions in the area of the sample, as a function of the multi-scale spatial sampling determined in step b); d) consecutively, for each spectrometry measurement position determined in step c), positioning the excitation beam and acquiring a spectrometry measurement; and e) reconstructing a spectrometry image point-by-point from the spectrometry measurements acquired in step d).
