Submillimeter receivers for radio astronomy

Proceedings of the IEEE, 1992
The state of development of receivers for submillimeter-wave radio astronomy is reviewed. Bolometers for continuum observation, hot-electron mixer receivers for narrowband spectral line observation, and heterodyne receivers, both Schottky diode and superconducting tunnel junction, are presented.

Low-pass interference filters for submillimeter astronomy

Applied Optics, 1980
Low-pass (long-wave transmitting) interference filters, suitable for broadband photometric observations, previously have been constructed from series of capacitive grids stretched on thin Mylar. These filters have the desired optical properties of high transmission, sharp cut-ons, and good blocking at short wavelengths.

Techniques of Submillimeter Astronomy

1988
This review discusses the relative merits of direct and heterodyne techniques for detection in the submillimeter band. A variety of astronomical observing conditions is examined, including those for mountain-top and space telescopes. The spectral resolution (Δν/ν) of the observation is shown to be an important factor in the decision between direct and ...
