Abstract: The optical verification of a terahertz superconducting spectrometer (TSR) featured with superconducting-insulator-superconducting (SIS) receivers developed at Purple Mountain Observatory (PMO) for atmospheric profiling synthetic observation system project (APSOS) has been presented. Near-fields of TSR at 230 GHz and 280 GHz have been measured and far-fields are derived. The misalignment of the optics at 280 GHz is analysed in detail by physical optics (PO).
Keywords: Superconducting receiver, Near-field, Physical optics, SIS.
