Abstract: In one embodiment, the disclosure relates to a method for interrogating a sample by: illuminating a first region of the sample with a first illumination pattern to obtain a plurality of first sample photons; illuminating a second region of the sample with a second illumination pattern to obtain a plurality of second sample photons; processing the plurality of first sample photons to obtain a characteristic atomic emission of the first region and processing the plurality of second sample photons to obtain a Raman spectrum; and identifying the sample through at least one of the characteristic atomic emission of the first region or the Raman spectrum of the second region of the sample.
