Wavelet Denoising for Infrared Laser Spectroscopy and Gas Detection

Not Accessible

Your library or personal account may give you access

Abstract

After a brief introduction to wavelet theory, this paper discusses the critical parameters to be considered in wavelet denoising for infrared laser spectroscopy. In particular, it is shown that measurement dispersion as well as sensibility can be dramatically improved when using wavelet denoising for gas detection by infrared laser absorption spectroscopy.
