A Scintillometer is a scientific device used to measure small fluctuations of the refractive index of air caused by variations in temperature, humidity, and pressure. It consists of an optical or radio wave transmitter and a receiver at both ends of an atmospheric propagation path. The receiver detects and evaluates the intensity fluctuations of the transmitted signal, called scintillation. scintillometer - find the meaning and all words formed with scintillometer, anagrams with scintillometer and much more.

A scintillometer is a scientific device used to measure small fluctuations of the refractive index of air caused by variations in temperature, humidity, and pressure.

It consists of an optical or radio wave transmitter and a receiver at opposite ends of an atmospheric propagation path. The receiver detects and evaluates the intensity fluctuations of the transmitted signal, called scintillation.

A field study with LASs of different aperture sizes and path lengths was performed to investigate the onset of, and corrections for, signal saturation.

Saturation already occurs at $${C_n^2 \approx D^{5/3} \lambda^{1/3} L^{-8/3}}$$, where $${C_n^2}$$ is the Cited by: Scintillometer definition, a device for detecting and measuring radioactivity, having a crystal scintillator, a photoelectric cell sensitive to the light from scintillations, and an amplifier.
