Abstract
An apparatus designed for generating and detecting reflected Terahertz waves using a single pixel Complementary Metal Oxide Semiconductor (CMOS) or Charge Couple Device (CCD) camera is described. Optical alignment between the components is not necessary since the Terahertz waves can propagate from the source to a collimating lens using a metal wire that can be bent obviating the need to have a clear line of sight from the lens to the source or to the camera. The present invention is well-suited for high traffic physical locations currently under surveillance such as security check points and also venues demanding significantly less obtrusive surveillance such as revolving entry doors, moving walkways, and entry gates for airplanes.
