An Atmospheric Refractive Index Fluctuation Meter,

Abstract

A modulated GaAs LED has been used as an incoherent source for a nonsaturating atmospheric refractive index fluctuation meter. Measurement of C(n)(2) in the range (1/10 to the 12th power to 1/10 to the 16th power) (1/m to the 2/3 power) can be made using optical ranges of order 50 to 200 meters. Further development may allow use of shorter ranges or measurement of lower values of C(n)(2).
