Webb1 mars 2024 · Terahertz (THz) imaging is widely recognized as a powerful tool in a large variety of applications in non-destructive inspection. This Special Issue of Sensors, entitled “THz Imaging and Sensors”, will be focused on design, improvement, and characterization of compact THz imaging and its implementation. Webb15 dec. 2009 · To determine the spatial resolution of the THz quasi-near-field real-time imaging system, a resolution test is performed by imaging a razor blade edge with 200 μm thickness. The polarization of the THz pulses is parallel to the edge of the razor blade. The THz image of the blade at the moment of its time domain maximum value is presented … WebbWe report improvements in the scanning speed and standoff range of an ultra-wide bandwidth terahertz (THz) imaging radar for person-borne concealed object detection. Fast beam scanning of the single-transceiver radar is accomplished by rapidly deflecting a flat, light-weight subreflector in a confocal Gregorian optical geometry.
