Abstract
Imaging at submillimetre-wave (SMMW) frequencies is of
considerable interest for security applications due to
potentially superior performance at longer stand-off
ranges in comparison to mm-wave imaging thanks to reduced
diffraction. We have demonstrated passive broad-band
video rate imaging system operating at a centre frequency
of about 600 GHz, capable of 10 frames/second imagery of
a 2 m * 1 m field-of-view at a stand-off distance of 5
meters. In addition, a multi-band system centred around
250, 450 and 720 GHz will be discussed. Multi-band
imagery is interesting given its potential for
rudimentary materials differentiation, a capability that
would substantially benefit e.g. security imaging
applications. The passive imaging activities are
complemented by activities towards developing rapid
electronic beam steering capability for imaging
submm-wave radars. Results from two projects aiming at
constructing such beam steering systems at 120 GHz and at
650 GHz are presented.
