    • Applications of Terahertz Imaging 

      Mittleman, Daniel M.; Neelamani, Ramesh; Baraniuk, Richard G.; Nuss, Martin C. (1998-08-01)
      The recent advances involving imaging with sub-picosecond terahertz pulses have opened up a wide range of possibilities in the applications of far-infrared technology. For the first time, a commercially viable terahertz ...
    • 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 ...
    • Imaging with Terahertz Pulses 

      Dorney, Timothy D.; Johnson, Jon L.; Mittleman, Daniel M.; Baraniuk, Richard G. (2000-07-01)
      Recently, a real-time imaging system based on terahertz (THz) time-domain spectroscopy has been developed. This technique offers a range of unique imaging modalities due to the broad bandwidth, sub-picosecond duration, and ...
    • Imaging with THz Pulses 

      Dorney, Timothy D.; Johnson, Jon L.; Mittleman, Daniel M.; Baraniuk, Richard G. (2000-09-01)
      A real-time imaging system based on terahertz (THz) time-domain spectroscopy has been demonstrated. This technique offers a range of unique imaging modalities due to the broad bandwidth, sub-picosecond duration, and ...
    • Recent advances in Imaging and Spectroscopy with T-rays 

      Mittleman, Daniel M.; Neelamani, Ramesh; Gupta, Maya; Baraniuk, Richard G.; Nuss, Martin C. (1998-12-01)
      Recent work in terahertz "T-Ray" imaging is reported. With the ongoing development of commercially viable THz-TDS imaging system, opitmail signal processing strategies for the THz waveforms must be developed. Algorithms ...
    • Recent Advances in Terahertz Imaging 

      Koch, Martin; Rudd, J. Van; Neelamani, Ramesh; Gupta, Maya; Baraniuk, Richard G.; Mittleman, Daniel M. (1999-06-01)
      We review recent progress in the field of terahertz "T-ray" imaging. This relatively new imaging technique, based on terahertz time-domain spectroscopy, has the potential to be the first portable far-infared imagin ...
    • Spectroscopic Imaging using Terahertz Time-Domain Signals 

      Dorney, Timothy D.; Baraniuk, Richard G.; Mittleman, Daniel M. (2000-04-01)
      Imaging systems based on terahertz time-domain spectroscopy offer a range of unique modalities due to the broad bandwidth, sub-picosecond duration, and phase-sensitive detection of the terahertz pulses. Furthermore, an ...
    • Terahertz Multistatic Reflection Imaging 

      Dorney, Timothy D.; Symes, William; Baraniuk, Richard G.; Mittleman, Daniel M. (2002-07-01)
      We describe a new imaging method using single-cycle pulses of terahertz (THz) radiation. This technique emulates the data collection and image processing procedures developed for geophysical prospecting and is made possible ...
