Abstract :
Active spectroscopic imaging is based on arrays of broadband, short-response-time detectors observing a scene illuminated by a number of THz sources. Here we present the system design, the fabrication process and the single-pixel test for three detector technologies: GaAs Schottky diodes, GaN transistors, Nb bolometers.
