Title: Atmospheric scattering from a 1.15-micron laser beam and its off-axis detectable range
Description: The detectability of a laser beam through a fog can be predicted fairly accurately for various detector and collecting optical systems if temperature, relative humidity, and fog extinction coefficient are known. Smoke is much more variable and can not be characterized by only its extinction coefficient. Fog and smoke angular scattering patterns determined experimentally are presented.
