Paper Abstract

Measurements of atmospheric turbulence, mainly for adaptive optical correction, are carried out today by using a reference source near the astronomical object. Laser-created guide stars are being tested as alternatives to scarce natural stars. It might be easier to obtain radio-created guide stars at high elevations. By interference of radio beams, visible plasma is created or modified in fine fringes, and their observation at multiple angles is used for tomography of the turbulence. Such guide stars might also be used for phasing radio-telescopes.
