Paper Abstract

The characteristics of pulse laser transmitting in atmosphere were analyzed. An experiment setup was introduced to measure the impacts of fog produced by ultrasonic-nebulizer on time delay characters of the laser pulse transmission in atmosphere. The experimental results show that the width of laser pulse becomes wider while the laser pulse transmits in fog. The value of width broadened increases with the enhancement of fog thickness. The value of width broadened is substantially proportional to the extinction coefficient. The R-square of curve fitting is 0.9777. This relation may be used to estimate the atmosphere extinction.
