TERAHERTZ SPECTRUM ANALYZER, CAPABLE OF OBTAINING SPECTRUM OF THZ CONTINUOUS WAVE

摘要

PURPOSE: A terahertz spectrum analyzer is intended to provide a precise THz spectrum analyzer based on absolute frequency and output measurement.;CONSTITUTION: An absolute frequency measuring unit measures absolute frequencies through a light heterodyne detecting technique using THz frequency combs as a local oscillator and a THz detector as a heterodyne detector. An absolute output measuring unit measures absolute output using the THz detector. A THz spectrum analyzer can obtain output spectrum of THz continuous wave based on absolute frequency and absolute output.;COPYRIGHT KIPO 2011
