A new type of light pulses timer allowing a direct locking within the electric oscillation delivered by a clock is presented. The light pulses to be timed cross an electro-optic crystal excited by an oscillating electric field, which modifies the light polarization.

Recent progress in statistical information optics: statistical information processing for optics
SPIE Proceedings, 2013In this paper, we reviewed our recent work on the statistical information processing for optics including coherence diffraction, mutual coherence tensor, and the associated propagation properties, which we recently proposed and experimentally demonstrated.

On the Nonlinear Statistics of Optical Flow
2018In A naturalistic open source movie for optical flow evaluation, Butler et al. create a database of ground-truth optical flow from the computer-generated video Sintel. We study the high-contrast \(3\times 3\) patches from this video, and provide evidence that this dataset is well-modeled by a torus (a nonlinear 2-dimensional manifold).

Optical Systems and Statistical Optics.
1982Abstract : Theoretical and experimental research is being conducted in the field of opto-electronic systems. The goal is to contribute solutions to problems of basic research importance which also have an underlying significance in practical applications that involve automatic pattern recognition and remote sensing.

Speckle statistics in optical coherence tomography
Journal of the Optical Society of America A, 2005The two previously reported calculations of the amplitude distribution of speckles in optical coherence tomography, each based on a different mathematical formulation, yield different results. We show that a modification of an initial assumption in one of the formulations leads to equivalent results.

Colloidal statistical mechanics in optical vortices
SPIE Proceedings, 2007Holographoc optical tweezers can be used to create a variety of optical landscapes in which particles can be trapped and driven. We study particles driven by optical vortices in the framework of non-equilibrium statistical mechanics.

Journal of the Optical Society of America, 1982
A statistical approach is taken toward the ray optics of optical media with complicated nonspherical and nonplanar surface shapes. As a general rule, the light in such a medium will tend to be randomized in direction and of 2n2(x) times greater intensity than the externally incident light, where n(x) is the local index of refraction.

Fading statistics for intersatellite optical communication
Applied Optics, 1997The narrow beam widths associated with intersatellite optical communication links make such links susceptible to signal fading because of pointing jitter. Such fading can be aggravated by stationary offsets in pointing. We calculated the fade rates for the case of two spaceborne telescopes having Gaussian beam profiles, a pointing offset, and pointing ...

Optical Chaos and Its Statistics
1984The output light from an optical cavity containing a nonlinear dielectric medium exhibits, with increase of the incident light intensity, transition from a stationary state to periodic and chaotic states.[1–11] In this paper we investigate the statistical properties of fully developed chaos which appears for extremely intense incident light.
