Abstract

Telescopes for submillimeter wavelengths have point spread functions some millimeters or centimeters in diameter, but the detectors may be only fractions of a millimeter in size. Thus a field aperture and collecting optics are needed. We show how to optimize the aperture by a calculation of the effects of diffraction on signal and resolution as a function of size of the collecting aperture. Our calculations are compared to experimental results from observations of Mars at submillimeter wavelengths.
