An Atmospheric Refractive Index Fluctuation Meter,

Pagination or Media Count:
A modulated GaAs LED has been used as an incoherent source for a nonsaturating atmospheric refractive index fluctuation meter. Measurement of Cn2 in the range 110 to the 12th power to 110 to the 16th power 1m to the 23 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 Cn2.
