    Abstract: An apparatus for analyzing, identifying or imaging an target including first and second laser beams coupled to a pair of photoconductive switches to produce CW signals in one or more bands in a range of frequencies greater than 100 GHz focused on and transmitted through or reflected from the target; and a detector for acquiring spectral information from signals received from the target and using a multi-spectral heterodyne process to generate an electrical signal representative of some characteristics of the target. The lasers are tuned to different frequencies and a frequency shifter in the path of one laser beam allows the terahertz beam to be finely adjusted in one or more selected frequency bands.

    Abstract: There is described an apparatus for analyzing, identifying or imaging a target. The apparatus comprises a laser system which generates first and second laser beams having respective different frequencies, and directs the first and second laser beams along an optical path to a photoconductive material. An antenna structure is formed on the photoconductive material, the antenna structure comprises a first antenna for emitting electromagnetic radiation having a frequency dependent on the difference between said respective different frequencies of the first and second laser beams and a second antenna for generating a detection signal. A processor processes the detection signal to analyze, identify or image the target. The laser system is arranged such that the first and second laser beams overlap in a region of a surface of the photoconductive material having at least part of the first and second antennas formed thereon.
