Optimization of the Rolling-Circle Filter for Raman Background Subtraction

Not Accessible

Your library or personal account may give you access

Abstract

A procedure is proposed to optimize a high-pass filter enabling one to subtract the broadband background signals inherent in Raman spectra. A spectral approach is used to analyze the characteristics of the filter and the distortions in the processed spectra. Examples of the processing of real spectra are presented.
