激光是六十年代初出现的一种新颖光源,由于具有单色性好、相干性强、方向性高以及大能量、大功率等特点,而日益广泛地应用于各个领域.近年来,激光在探测大气污染方面也日益显示出很大优越性,并已实际应用于大气污染监测和大气污染扩散的研究。激光遥测烟云和大气尘埃,就是激光 Laser is a kind of novel light source appearing in the early 1960s, which has been widely used in various fields due to its good monochromaticity, strong coherence, high directivity and high energy and high power. In recent years, Detection of atmospheric pollution has also shown a great advantage, and has been actually applied to the monitoring of air pollution and air pollution research. Laser telemetry clouds and atmospheric dust, is the laser
