Technology background

All ThruVision Systems’ products are passive.  Images of concealed objects on people are formed by receiving low energy waves known as terahertz waves.  Terahertz waves occupy part of the electromagnetic spectrum between radio waves and infra-red (heat).  Terahertz waves are naturally produced all of the time by all objects and people. ThruVision Systems’ products only receive, they do not transmit.  ThruVision Systems’ products do not illuminate people with any radiation such as X-rays or millimetre wave microwaves. The products provide imaging solutions for real time use on people either close by or at distance, indoors and out.  This technology was originally derived from work pioneered for space imaging applications within the UK at the Rutherford Appleton Laboratory, now part of the Science and Technology Facilities Council, supported by a programme from the European Space Agency.
