  • Abstract
    Terahertz digital off-axis holography is demonstrated with a highly coherent, frequency tunable continuous wave terahertz source emitting between 0.1 and 0.8 THz and a single spatially-scanned Schottky diode detector. The angular spectrum and dual wavelength reconstruction methods are employed for the digital reconstruction process.
