Paper Abstract

A telescope-mounted wavefront-folding interferometer designed to measure the phase fluctuations due to atmospheric seeing on a wide range of temporal and spatial scales is described. It makes use of photon-counting avalanche photodiodes to achieve high SNRs at high sampling rates. In addition to testing theories of the atmospheric turbulence responsible for the seeing, instrumental effects such as telescope vibrations can be quantified.
