Atmospheric phenomena such as scattering and turbulence can cause large variation in laser beam attenuation of free space optics systems. The paper deals with comparison of the atmospheric attenuation caused by both these phenomena and with comparison of the link availability affected by scattering at 850 nm and 1550 nm. The dispersive behavior of the atmosphere is modeled using the Mie scattering...
This paper examine about the selecting of wavelength in effecting the laser transmission over the free space spatial under the rain circumstances. The wavelengths used in these computation experiment theory are 780 nm, 850 nm, 1550 nm and 10000 nm. Comparison of the experiment result is measured in various types of rain such as drizzle, light rain, medium rain, heavy rain, cloudburst, extreme rain...
