TLDR
Puryear et al. as mentioned in this paper introduced and analyzed the exploitation of atmospheric reciprocity for combating turbulence, and presented reciprocity proofs that apply under rather general conditions and underlie the communication performance analysis.Abstract:
Turbulence-induced scintillation is the principal impairment to Gbps laser communication over clear-weather
atmospheric paths. This paper, plus its companion [A. Puryear, J. H. Shapiro, and R.R. Parenti, “Reciprocity-
Enhanced Optical Communication through Atmospheric Turbulence—Part II: Communication Architectures
and Performance”], introduce and analyze the exploitation of atmospheric reciprocity for combating turbulence.
Part I presents reciprocity proofs that apply under rather general conditions and underlie the communication
performance analysis in Part II.read more

Enhancing the security of free-space optical communications with secret sharing and key agreement
TL;DR: Numerical results reveal that the key rate is not sensitive to the strength of the atmospheric turbulence; the per-symbol signal-to-noise ratio and the training sequence length are the dominating factors.

Electromagnetic beam propagation in turbulent media
TL;DR: In this article, the most recent developments on the propagation of optical beams in a turbulent medium, such as the clear atmosphere, are reviewed, including beam spreading, beam wander, loss of coherence, scintillations, angle-of-arrival variations, and short-pulse effects.

R. Q. Fugate,David L. Fried,Guillermo A. Ameer,B. R. Boeke,B. R. Boeke,S. L. Browne,P. H. Roberts,R. E. Ruane,R. E. Ruane,Glenn A. Tyler,L. M. Wopat +10 more
TL;DR: In this article, the authors showed that the mean square wavefront error created by using an artificial guide-star at a finite distance rather than a real (infinitely distant) star is proportional to the five-thirds power of the telescope aperture.

Analytic Solution of Two Apodization Problems
TL;DR: In this article, analytic solutions are given to the problem of determining the distribution of light in the exit pupil to concentrate maximally the illuminance in a geometrically similar region of the image plane.

Reciprocity of the Turbulent Atmosphere
TL;DR: In this article, the reciprocity theorem of Helmholtz is extended to the clear turbulent atmosphere and two impulse responses (Green's functions) are defined to characterize optical propagation in opposite directions between two parallel planar apertures separated by the turbulent atmosphere.
