Wide field Raman imaging using the integral field spectroscopy approach was used as a fast. one shot imaging method for the simultaneous collection of all spectra composing a Raman image. For the suppression of autofluorescence and background signals such as room light. shifted excitation Raman difference spectroscopy (SERDS) was applied to remove background artifacts in Raman spectra. https://www.spidertattooz.com/Messerschmitt-Me262A-1A-Fighter-Aircraft-LT-Walter-Hagenah-III-Jagdeschwader-7-Larz-Airfield-Germany-1945-German-Luft/
