An optical scintillometer was built to measure the refractive index structure parameter (CN2) and the wind speed across the transmission path. The device uses a LED (light emitting diode) at 0.94 μm as a light source and simple semiconductor light detectors. The aim of this report is to give a brief description of the scintillometer and some results we got with it on a test path of 449 m at Cabauw, The Netherlands.
