ABSTRACT:
A method and apparatus for transmitting laser signals through fog, in which a laser signal directed into the fog is amplitude modulated at one or more resonant frequencies of the water droplets forming the fog at such strength as to cause the droplets to burst, thereby decreasing the scattering of the laser signal and increasing the transmission of this signal through the fog.
