Barcelona, 2010.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.6 p.application/pdfengTerahertz camerasResolution improvementCharge-couple devicesinfo:eu-repo/semantics/conferenceObjectAcceso abierto / Sarbide irekiainfo:eu-repo/semantics/openAccess
