Paper Abstract

We report on the development of a portable, battery-operated terahertz spectrometer designed for reflection-mode or transmission-mode studies of materials in a wide range of applications. We discuss the challenges overcome to achieving low cost and compact form-factor for the spectrometer instrument, by leveraging commercial fiber-optic packaging techniques for the lasers and photomixers. This approach also permits the THz source and sensor heads to be located remotely from the processing and control electronics. We also discuss novel optical THz phase-control and frequency calibration methods employed in the system.
