A saturation-resistant optical scintillometer to measure Cn2†

Abstract

This paper describes a new optical technique for measuring the refractive-index structure parameter $C_n^2$. By using relatively large incoherent transmitting and receiving optics, the scintillometer maintains its calibration and path-weighting function throughout the range of observed refractive turbulence values, even to the case of saturated scintillation.
