Scientific paper

This paper investigates the technical feasibility of conducting submillimeter interferometry measurements (which are of primary importance for studying star formation and the structure and nuclei of galaxies and quasars) at the Mauna Kea Observatory, by connecting the existing and planned optical/IR telescopes and submillimeter telescopes. The instrumental system under consideration uses a heterodyne interferometry technique, which makes it possible to obtain a frequency resolution good enough for submillimeter wave spectroscopy. Attention is given to the four telescopes at Mauna Kea which can be used for a submillimeter interferometer, the telescope-array configuration, and the receiver system. A block diagram of the heterodyne interferometer is presented.
