TL;DR: In this paper, the authors present an airport surface traffic surveillance and automation system using a combination of runway status lights, controller alerts, and enhanced controller displays, which are used to direct a controller's attention to existing conflicts between aircraft on or near the runways.

TL;DR: In this paper, a set of concise analytic models describing the essential properties of a laser-guide-star phase-conjugation system has been assembled, and an optimization strategy for mating adaptive optics to a 4m-class optical telescope is evolved, and it is shown that such a system might be expected to improve the effective atmospheric seeing conditions within the isoplanatic patch of the turbulence probe.

TL;DR: In this article, the authors present a theoretical structure that accurately describes far-field irradiance fluctuations caused by uncorrected beam wander, which is validated by demonstrating excellent agreement between the predicted scintillation index and computer code results for both tracked and untracked beams.

TL;DR: In this article, the authors use the Rytov approximation and filter functions in the spatial domain to express quantities of interest such as Zernike modes and effects of anisoplanatism for single or counter-propagating or copropagating plane or spherical waves in integral form.

TL;DR: Analytical expressions that can be used to determine performance in a variety of geometries, with various beacon altitudes and numbers, are derived in adaptive optics systems applied to 60-cm and 4-m systems.
