THz technology for developing imaging
systems has recently aroused great interest, mainly due
to the large number of applications in which these
frequencies can be used: security, vision in hard
environments, etc.
In this paper we propose a method that reduces
significantly the number of detectors needed for
achieving certain resolution by means of diffraction that
paradoxically is its main limiting factor in current
imaging devices. The method uses diffraction as a way
of achieving spatial diversity and as an anti-aliasing
LPF. Decimation is used to reduce the number of
detectors.
