Abstract: Disclosed is a method of acquiring and forming a spectrometry image of a sample including the following steps: e1) acquisition of an initial image, composed of pixels, of an area of the sample and definition of a maximum set of N, 2≤N, measurement positions of spectrometry, each measurement position including a coordinate and an intensity determined on the basis of the pixels; e2) assignment of a classification value to each of the N measurement positions on the basis of deviations, calculated based on an intensity difference and a coordinate difference, between the measurement positions; e3) determination of a group of P, 1≤P≤N, measurement positions as a function of the classification values; e4) successively, for each measurement position of the group, positioning of an excitation beam in the measurement position on the area of the sample, acquisition of a spectrometry measurement and formation of the spectrometry image.

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).
