WebbRaman imaging is build upon the combination of two powerful analytical techniques: Raman spectroscopy and microscopy. In Raman spectroscopy, the information of inelestically scattered monochromatic (laser) light is used to investigate the chemical nature of matter. This process is non-destrucive and even non-contact by default. WebbSome techniques of modern laser spectroscopy employ frequency combs as generated with mode-locked lasers [12]. As such a frequency comb contains some number of exactly equidistant lines in the spectrum, all of its frequency components are known (apart from some noise) if only two parameters are fixed (possibly stabilized with some feedback … WebbWhat is Raman Spectroscopy? The Raman effect describes the inelastic scattering of light at matter, during which energy is exchanged. Chemical data can be easily obtained by interpreting this contact-free and non-destructive spectroscopic technique. Learn more. 地鶏たたきレシピ
