How do atmospheric conditions have an impact on FSO transmissions?
What will be an ideal response?
Scintillation is the temporal and spatial variations in light intensity caused by atmospheric turbulence. Turbulence caused by wind and temperature variations can create pockets of air with rapidly changing densities. These air pockets can act like prisms and lenses that distort an FSO signal. Inclement weather is also a threat. Although rain and snow can distort a signal, fog does the most damage to light based transmissions. Fog is composed of extremely small moisture particles that act like prisms, scattering and breaking up the light beams.
