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 the advantages
of the spatial diversity (information spread over a set
of detectors) giving also the possibility to increase the
resolution of the obtained images interpolating samples
between detectors thanks to the slow variation function
created by the diffraction phenomena. [--]
