    • Gas Sensing using Terahertz Time-Domain Spectroscopy 

      Mittleman, Daniel M.; Jacobsen, R. H.; Neelamani, Ramesh; Baraniuk, Richard G.; Nuss, Martin C. (1998-01-15)
      A method for detection and identification of polar gases and gas mixtures based on the technique of terahertz time-domain spectroscopy is presented. This relatively new technology promises to be the first portable far-infared ...
    • Improved Tuning Fork for Terahertz Quartz-Enhanced Photoacoustic Spectroscopy 

      Sampaolo, Angelo; Patimisco, Pietro; Giglio, Marilena; Vitiello, Miriam S.; Beere, Harvey E.; Ritchie, David A.; Scamarcio, Gaetano; Tittel, Frank K.; Spagnolo, Vincenzo (2016)
      We report on a quartz-enhanced photoacoustic (QEPAS) sensor for methanol (CH₃OH) detection employing a novel quartz tuning fork (QTF), specifically designed to enhance the QEPAS sensing performance in the terahertz (THz) ...
    • Quartz-Enhanced Photoacoustic Spectroscopy: A Review 

      Patimisco, Pietro; Scamarcio, Gaetano; Tittel, Frank K.; Spagnolo, Vincenzo (2014)
      A detailed review on the development of quartz-enhanced photoacoustic sensors (QEPAS) for the sensitive and selective quantification of molecular trace gas species with resolved spectroscopic features is reported. The basis ...
