Interferometry and Aperture Synthesis

  • Chapter

Abstract

The resolution of a telescope has a diffraction limit of ∼λ/D, where λ is the observing wavelength and D is the aperture diameter. The resolution of large optical telescopes is limited to about a half arc second by atmospheric fluctuations, although the diffraction limit is much smaller. However, for radio frequencies a diffraction limit of about 1 arc minute at the highest radio frequencies is currently reached using filled-aperture telescopes. Further significant increase of the resolution of filled-aperture telescopes is not likely.
