The invention relates to a method for electromagnetic spectroscopy of a sample, the method comprising: - Delivering an excitation beam of electromagnetic radiation to a first portion of a sample to obtain emission, or elastic or inelastic scattering of photons, said photons having a wavelength in the visible range, from molecules forming the sample; - Illuminating the first portion of the sample with a visible light, said visible light being switched on and off at a first frequency, so that illuminated time intervals and non-illuminated time intervals of the sample are defined; - Detecting said emitted, or elastically or inelastically scattered photons having a wavelength in the visible range during said non-illuminated time intervals; and - Obtaining spectroscopy information from said detected emitted, or elastically or inelastically scattered photons. It also relates to a system for electromagnetic spectroscopy of a sample. |
