Terahertz Reflection Spectroscopy for Identification of Explosive Devices

Abstract

The research conducted under this project was a joint effort between Applied Physics Laboratory, University of Washington (APL-UW), and Portland State University (PSU). The focus at APL-UW was on 1) developing an experimental setup for variable source and detector angles and variable linear polarization, and then implementing it on a commercial THz spectroscopic system at PSU, 2) expanding the current THz time domain spectroscopic system at APL-UW to cover broader bandwidth by developing an air plasma THz source, and 3) developing analysis techniques that allow spectroscopic signatures to be recovered in the presence of appreciable background noise, a situation that can be expected when volume and rough surface scattering processes are important. The long-term goal of this project has been to lay the groundwork for an integrated spectral and imaging methodology on which to base technology development.
