A new high‐resolution device for infrared astronomy is being developed at the University of California at Berkeley by Charles Townes and his collaborators, Michael Johnson, Albert Betz and Daniel Galehouse. Applying the new Techniques of quantum electronics to a concept originated by Albert A. Michelson, they have built the first infrared stellar interferometer. Townes expects an angular resolution to be orders of magnitude greater than that of an ordinary telescope. It will be used to measure the size and shape of stars and other astronomical objects.
