Atmospheric optical communications systems

Proceedings of the IEEE, 1970
The increasing sophistication of optical (and infrared) components and techniques, combined with rapidly expanding communication requirements, suggests that optical systems operating partly or entirely within the atmosphere may soon represent desirable solutions to real communications problems.

Fiber-optic atmospheric turbulence sensor

Optics Letters, 1995
A 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 ...

Atmospheric Optical Communication System

IEEE Transactions on Communications, 1977
The prototype atmospheric optical communication system has been developed, and various field tests have been carried out in Tokyo and Niigata. The system with a laser diode can transmit a 4-MHz color television signal or 120 telephone channels. This paper gives an outline description of system design based on field test results.

Optics of Atmospheric Haze

Journal of the Optical Society of America, 1941
By means of a telescopic photometer measurements were made in daylight of b, the brightness of a large approximately blackbody at a distance d=3.2 km, and of h, the brightness of the sky just above the blackbody. For visual ranges v from 3.2 to 15 km the measurements agreed with the theoretical relations v=(1/β) log 1/η and β=(1/d) log (1/(1−b/h ...
