Abstract

The variance of intensity of stellar scintillation has been measured as a function of wavelength using photon counting and on-line digital analysis techniques. The experimental data are consistent with that predicted by the theory of Tatarski. Measurements of the temporal correlation function of intensity and the higher moments of the probability density function of scintillation are also described. Time scales in the 1.7–10-msec range were observed, and the observed higher moments were consistently lower than those predicted by a log normal distribution. All the measurements were made at Mauna Kea Observatory, Hawaii.
