OPTICAL EFFECTS OF NEAR-GROUND TURBULENCE AT THE VAN NORMAN LAKE SOLAR OBSERVATORY SITE.
Abstract
The distortion of light wavefronts by atmospheric turbulence in the first 15 m above ground was measured at a solar observatory site near Sylmar, California. It is inferred from these data that seldom if ever should near-ground turbulence significantly degrade the resolution of a solar telescope to be installed at this site. Comparison of the measured values of near-ground turbulence with simultaneous estimates of solar 'seeing' quality showed essentially no correlation between the two variables. The instrument used to measure wavefront distortion, a 'differential-interferometer seeing meter' being developed in these laboratories, is described.
