Kinds of array telescope :

• Optical Very Large Array (2 facts) (OVLA)
• radio interferometer (3 kinds, 22 facts) - Type of radio telescope that relies on the use of two or more aerials at a distance from each other to provide a combination of signals from one source which can be analyzed by computer. Such an analysis results in a resolution that is considerably better than that of a parabolic dish aerial by itself because of the greater effective diameter.
• Very Large Telescope (20 facts) (VLT)
• Very Large Telescope Interferometer (2 facts) (VLTI)
