One embodiment relates to an analyzer having an interferometer, a detector and a microprocessor, wherein the analyzer does not contain a spectrometer having a dispersive grating, the interferometer is to create a phase shift in an original spectrum of electromagnetic radiation emitted from a sample and Fourier transform the original spectrum to a Fourier transform spectrum, the detector is to detect a characteristic of the Fourier transform spectrum, and the microprocessor comprises software or a hardware to inverse transform the Fourier transform spectrum and reproduce the original spectrum. Another embodiment relates to a Raman analyzer having an interferometer, wherein the Raman analyzer contains no dispersive grating or moving parts and has an ability to analyze a Raman signal. The embodiments of the invention could be used for analyzing a sample by striking a laser to the sample and examining the spectrum of the emitted electromagnetic radiation from the sample.
