Interferometers are groups of telescopes that have been linked together and interfere the light waves that they receive to achieve the same angular resolution (but not the collecting area)  as a much larger telescope. An example is the Very Large Array in New Mexico, which links 27 telescopes, each the size of a large house, over tens of miles.
