fluctuation of air refractive index, is compensated by feedbacks from the reference interferometers. The measured optical path length is then locked to certain atmosphere, resulting in index of refraction fluctuations (i.e., optical turbulence). Theoretical and experimental studies of irradiance fluctuations generally center. During these experiments we observed the nature of the fluctuating refractive index of air through the recorded length noise over a measuring range (beam path) 19 Jul 2013 Interferometric Spectroscopy of Scattered Light Can Quantify the Statistics of Subdiffractional Refractive-Index Fluctuations.

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 . 9 Apr 2018 Power spectrum of refractive-index fluctuations in turbulent ocean and its effect on optical scintillation. Xiang Yi and Ivan B. Djordjevic. The dependence of fluctuations in atmospheric absorption and refraction upon fluctuations in temperature, humidity, and pressure is found for infrared frequencies.
The practical limit in evaluation of the refractive index of air is determined by effects such as thermal gradients and air fluctuations. They cannot be completely avoided; they depend on particular application and measurement configuration.
Our data indicates that the refractive index distribution of histopathology slides, which contains information about the molecular scale organization of tissue, reveals prostate tumors. These optical maps report on subtle, nanoscale morphological properties of tissues and cells that cannot be recovered by common stains, including hematoxylin and eosin (H&E). The presence of refractive index fluctuations in an optical medium can result in the generation of optical rogue waves. Using numerical simulations and statistical analysis, we have shown that the probability of optical rogue waves

They cannot be completely avoided; they depend on particular application and measurement configuration. Effects of temperature and humidity fluctuations on the optical refractive index in the marine boundary layer Article (PDF Available) in Journal of the Optical Society of America 65(12):1502-1511 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.
