Long Michelson Interferometer
Encyclopedia
The Long Michelson Interferometer was a radio telescope
interferometer built by Martin Ryle
and co-workers in the late 1940s beside the rifle range to the west of Cambridge
, England. The interferometer consisted of 2 fixed elements 440m apart to survey the sky using Earth rotation. It produced the Preliminary survey of the radio stars in the Northern Hemisphere at 45 MHz - 214 MHz. The telescope was operated by the Radio Astronomy Group
of Cambridge University
.
Martin Ryle
and Antony Hewish
received the Nobel Prize for Physics in 1974 for this and later work in radio interferometry.
