Atmospheric coherent turbulence
Atmospheric and Oceanic Optics, 2012This paper summarizes results received by authors for last decade on the problem of the atmospheric coherence turbulence. Also shows some new results of the unpublished researches. According to our data the coherent turbulence is the result of the self-organizing non-linear processes in continuous media, including in the atmospheric air.

AbstractEvidence which has accumulated shows that the classical theory of atmospheric turbulence which assumes thatKthe coefficient of eddy diffusion is constant with height is inadequate to explain the observed variations of wind and temperature with height.

Restoring atmospheric-turbulence-degraded images
Applied Optics, 2016Image data experiences geometric distortions and spatial-temporal varying blur due to the strong effects of random spatial and temporal variations in the optical refractive index of the communication path. Simultaneously removing these effects from an image is a challenging task.

In-flight investigations of atmospheric turbulence
Aerospace Science and Technology, 1998Abstract One of the key technologies in aeronautics offering substantial improvements in the fields of economy and ecology is the laminar flow technology. The sensitivity of the laminar boundary layer flow over aerodynamically smooth surfaces to the effects of disturbances like noise, vibration and insect contamination as well as the atmospheric ...

Atmospheric turbulence mitigation based on turbulence extraction
2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016A video taken under the influence of atmospheric turbulence suffers from serious distortion caused by the variation of optical refractive index. In order to reduce geometric distortion and time-space-varying blur, and recover both coarse structure and fine details, a novel turbulence extraction based approach for recovering a latent image from an ...

Fiber-optic atmospheric turbulence sensor
Optics Letters, 1995A novel dual-air-gap fiber-optic Mach - Zehnder interferometer is proposed for the direct measurement of the atmospheric optical turbulence structure constant C(n)(2). The shot-noise-limited minimum detectable structure constant is estimated to be 4.5 x 10(-20) m(-2/3), which is more than 2 orders of magnitude below a typical value of 10(-17) m(-2/3 ...
