Researchers at The University of Queensland (UQ) have developed a technology that constitutes a major leap beyond the current commercially available systems. UQ researchers have developed a laser feedback interferometric (LFI) transceiver based on a terahertz (THz) quantum cascade laser (QCL) utilising patent pending technology.  The transceiver is built around a small footprint (~2mm) THz QCL and provides a clear pathway towards commercially viable, low maintenance THz sensing and imaging systems.

The THz frequency band is the most recent portion of the electromagnetic spectrum to be technologically harnessed for imaging and sensing applications.  While significant advancements have been achieved in deploying sensors and full-body scanners operating at millimetre-wave frequencies, access to the genuine THz spectrum (1-10 THz) will be required for the next generation of high-performance, high resolution imaging and sensing systems.

Key benefits:

  • High-resolution, high frame-rate imaging
  • Compact and simple: THz illuminator and camera in one package
  • High sensitivity and high power.
