Abstract：Aim at the phenomena of unclear practical intent and slow data analysis in process of atmospheric detection by micro-pulse lidars, the principle and structure characteristics of the lidars were analyzed and their development status and actual application examples were discussed on the basis of status and key technology of basic applications. It is shown that micro-pulse lidars have the characteristics of low power, low cost, long-term stability, which are suitable for long-term, continuous detection of atmospheric particulate matter. The key links in the application of micro-pulse lidars are to control the validation and quality of data. In order to ensure the accuracy of detection information, the data quality must be strictly controlled in the original signals of sampling and the computing algorithm of further inversion for extinction coefficient, particle concentration, etc.
