The Group has been involved in PMMWI for many years, particularly in conjunction with the Passive Imaging Group at QinetiQ, Malvern, led by Dr Roger Appleby.  We have supplied a number of quasi-optical components to QinetiQ (DERA in the past), such as Faraday rotators, which have been incorporated into passive imagers operating in Ka- and W-bands.

Recent work on PMMWI has concentrated on close-focussed, diffraction limited imaging for high resolution mapping of sub-surface temperature of medical subjects.  The early research in the group by Dr David Macfarlane led to the development of MISTM, the Medical Imager for Sub-surface Temperature Mapping, by Dr Duncan Robertson in the Photonics Innovation Centre within the School of Physics & Astronomy.  MISTM is a fully functional turnkey imager which is currently undergoing hospital data gathering trials at Ninewells Hospital, Dundee.

We are currently developing a combined dual-mode imaging instrument which combines an FMCW radar with a passive radiometer, called AVTIS for All-weather Volcano Topography Imaging Sensor.  AVTIS is designed to map the topography and thermal profile of volcanic lava domes.
