Abstract: Disclosed is an optical micro-spectrometry system including an optical microscope, a spectrometry system and an optical system adapted to direct an excitation light beam on the sample through the at least one microscope objective and to collect a Raman or PL light beam from a sample. The optical micro-spectrometry system includes an imaging system configured for acquiring a first image and a second image of the sample, by reflection or transmission of an illumination beam from a sample surface, the first image having a large field of view and the second image having a small field of view, a processing system configured for determining an area in the first image corresponding to the second image, a display system configured for displaying the first image, the second image, and a third image representing the area in overlay on the first image.

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.
