Abstract
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.
