摘要
Abstract
Raman imaging is a kind of modern testing technology based on Raman scattering,which has been widely applied in manufacturing and scientific research.However,due to the fluorescent effect and instruments drift,the baseline shift could easily occur,which has a strong impact on the feature extraction of the Raman signals.Therefore,the baseline correction is necessary and inevitable in the signal processing of Raman spectra.The traditional baseline correction methods can only correct the Raman spectrum one by one,so once a large amount of Raman imaging signals have to be processed,the processing time is too long to accept.In this paper,the baseline correction base on comparison which considers the correlation between the Raman spectra and the same background is proposed to realize the fast baseline correction and improve the processing speed of Raman imaging data.关键词
