Terahertz imaging
WebIn terahertz imaging, lateral and axial resolution must be distinguished. Lateral resolution is primarily dictated by the wavelength used. Due to the frequency range used, the wavelength 3 mm (100 GHz) ranges from 100 µm (3 THz). Other factors that determine lateral resolution are the optics used and the imaging concept employed. WebJun 3, 2016 · We demonstrate noninvasive, near-field THz imaging with subwavelength resolution. We project a time-varying, intense (>100 μJ/cm 2) optical pattern onto a silicon wafer, which spatially modulates the transmission of synchronous pulse of THz radiation.
