Basic Principles Atmosphere / scintillometers + Expand this section to read more

Turbulance in the air affects the propagation of electromagnetic waves. The turbulance caused by fluctuations of temperature, moisture, pressure and their interactions can be measured with a scintillometer, thereby indicating the atmospheric turbulen...

Advantages Atmosphere / scintillometers + Expand this section to read more

Since the air being measured is continually moving the sample being measured is a very good average - in contrast to conventional equipment that must use large time intervals to sample adequately. There are no moving parts, and the presence of the s...

Details Atmosphere / scintillometers

In more detail, the phenomenon of optical scintillation is caused by fluctuations of the refractive index in the air - caused in turn by changes in density, pressure and moisture contetn of the air.
