Millimeter-Wave and Terahertz Imaging in Security Applications

  • Chapter
  • First Online:
Terahertz Spectroscopy and Imaging

Part of the book series: Springer Series in Optical Sciences ((SSOS,volume 171))

Abstract

The relatively short wavelength of mm-wave and THz radiation coupled with good transmission through many dielectric materials allows images to be formed of concealed objects. This chapter gives an overview of the detectors, their associated circuitry, and system developments over the past 10 years, focussing on personnel security screening. We will discuss the phenomenology of imaging at these wavelengths, introduce the reader to the basic architectures being used and developed for image forming instruments, show examples of systems, and also discuss the feasibility of spectroscopic THz imaging for security screening applications.
