A Lab VIEW Based Virtual Instrument for Background Correction of Spectrum for Chemical Identification

Nikita Chauhan, Payal, Reji Thomas

Raman Spectroscopy is a technique for obtaining the chemical information from the spectral analysis of a chemical. By analyzing the spectra, it is observed that there is background interference which occurs mainly by fluorescence and noise. Fluorescence reduction is of main concern in extracting the true spectra of a chemical. In this paper, we discuss about fluorescence present in the spectra obtained after performing Raman spectroscopy, various previous methods used for fluorescence subtraction and that not only corrects the baseline but smoothens the corrected output resulting in extraction of a true baseline spectrum. In this paper we develop a Lab VIEW based VI for baseline correction and display result in a user friendly GUI
