An Optical Device for Measuring Refractive-Index Fluctuation in the Atmosphere,

Abstract

An instrument is described that measures the average value of the refractive-index structure constant (C sub n squared) over optical paths from 80 to 800 meters. Corrections for the inner scale of turbulence and difficulties due to the saturation of scintillation, both present in previous optical techniques, are avoided by using an extended incoherent light source.
