  • Abstract
    This paper describes a spectroscopic system for gas sensing applications. It is based on SiGe transmitters (TXs) and receivers (RXs) operating at frequencies around 245 GHz and 500 GHz. 2f spectra of volatile organic compounds (VOCs) were obtained using wavelength modulation spectroscopy (WMS). Chemometrical analysis of the spectra is performed by applying several multivariate analysis (MVA) techniques.
