A method for obtaining chemical and/or material specific information of a sample based on scattered light. The method comprises receiving detection data comprising at least two images. Each image is indicative of the intensity of scattered light i) for incident light of a different wavelength, or ii) for incident light of a different polarization state, or iii) of a different polarization state. The scattered light comprises an elastic scattering component that is due to Rayleigh scattering of the incident light in at least a portion of the sample. Alternatively, each image is indicative of the intensity of scattered light i) of a different wavelength, or ii) for incident light of a different polarization state, or iii) of a different polarization state, wherein the scattered light comprises an inelastic scattering component that is due to Raman scattering of the incident light in at least a portion of the sample. The method further comprises determining the chemical and/or material specific information of the sample based on the change in intensity of the elastic scattering component in dependence on the change in wavelength and/or the change in polarization state of the incident and/or scattered light.
