Interferometry and Aperture Synthesis

  • Rosa PoggianiEmail author
Part of the UNITEXT for Physics book series (UNITEXTPH)


Interferometry with arrays of telescopes or antennas achieves angular resolutions that are not in the reach of single instruments. The present chapter discusses the principles of interferometry that are the foundations of both optical/infrared and radio interferometry. The concept of coherence is discussed, together with the technique of aperture synthesis.
