    The measurement of scattered signals at W Band can be exploited to form images of small deformations with precisions in the order of tenths of micrometers. In this paper an Interferometric Synthetic Aperture Radar setup ...
  • Retina design for 100GHz MST imaging system 

    Alonso, Maria; Garg, V.; Nova, Enrique; Abril, Jordi; Romeu Robert, Jordi; Llombart, Nuria; Jofre Roca, Lluís (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    Conference report
    Restricted access - publisher's policy
    A near field imaging system for THz tomographic imaging based on a MST retina (an array of real antennas) has been designed. The main adva ntage of this implementation is the absence of microwave transmission line ...
  • Teraherz subsurface imaging system 

    Nova, Enrique; Abril, Jordi; Guardiola Garcia, Marta; Capdevila Cascante, Santiago; Broquetas Ibars, Antoni; Romeu Robert, Jordi; Jofre Roca, Lluís (2010)
    Conference report
    Open Access
    A subsurface imaging system based on a terahertz time-domain spectrometer (THz-TDS) is described in this paper. The system performance has been simulated in terms of spatial resolution, penetration capabilities and SNR. ...
  • The “challenging” world of Terahertz radiation and imaging 

    Jofre Roca, Lluís; Romeu Robert, Jordi; Capdevila Cascante, Santiago; Abril, Jordi; Nova, Enrique; Alonso, Maria (2011)
    Conference report
