2012 IEEE Conference on Computer Vision and Pattern Recognition, 2012
Turbulence near hot surfaces such as desert terrains and roads during the summer, causes shimmering, distortion and blurring in images. While recent works have focused on image restoration, this paper explores what information about the scene can be extracted from the distortion caused by turbulence.

Controlling optical turbulence
Physical Review A, 1997A robust global control strategy, implemented as a spatial filter with delayed feedback, is shown to stabilize and steer the weakly turbulent output of a spatially extended system. The latter is described by a generalized complex Swift-Hohenberg equation [J. Lega, J. V. Moloney, and A. C. Newell, Phys. Rev. Lett.

2007 European Conference on Lasers and Electro-Optics and the International Quantum Electronics Conference, 2007
We consider the suppression of the so-called "turbulent regimes" in optical systems with advection. It is well known that spatiotemporal systems submitted to advection can undergo a convective instability above a critical value of the drift parameter.

SIMO detection schemes for underwater optical wireless communication under turbulence
Photonics Research, 2015 In underwater optical wireless communication (UOWC), a channel is characterized by abundant scattering/absorption effects and optical turbulence. Most previous studies on UOWC have been limited to scattering/absorption effects.

Weak Optical Turbulence in Class-A Nonlinear Optical Systems
EQEC'96. 1996 European Quantum Electronic Conference, 1996Transverse pattern formation and weak optical turbulence is theoretically investigated in multi-transverse-mode class-A nonlinear optical systems (primarily class-A lasers). It is shown, that "nontrivial patterns" occur due to transverse mode locking to a common frequency in class-A nonlinear optical systems.

Synthesis of anisotropic optical turbulence at the laboratory
Optics Letters, 2016At the foundation of the problem of light propagation through optical turbulence is the classical Obukhov-Kolmogorov theory. It rests in the requirement that the refractive index fluctuations should be homogeneous and isotropic. These, with other necessary assumptions, lead to the very well-known -11/3-power exponent spectrum on the inertial range ...

An optical study of turbulence
Journal of Fluid Mechanics, 1970This paper describes theoretical and experimental work carried out at the Cavendish Laboratory of the University of Cambridge. The main object of the work was to develop a new technique for measuring the structure of fluid turbulence.A parallel beam of light is passed through the turbulent region, containing refractive index fluctuations, and analyzed ...

Trajectory of an optical vortex in atmospheric turbulence
Physical Review E, 2009Trajectory of an optical vortex has been identified for its propagation in atmospheric turbulence using numerical simulations. An analytical expression has been found, relating the radial departure of the vortex in plane perpendicular to the direction of propagation, to the refractive index structure function parameter and the inner scale of turbulence.
