Abstract:Atmospheric lidar techniques, featuring high spatiotemporal resolution, and high sensitivity, have been widely used for atmospheric aerosol, trace gases, temperature and wind speed measurements since decades. The Scheimpflug lidar technique, based on the Scheimpflug imaging principle, has been recently developed for atmospheric remote sensing. The entire laser beam that is transmitted into atmosphere can be clearly focused over km-range on a tilted image sensor, if the optical configuration satisfies the Scheimpflug principle. The range-resolved lidar signal is in this case angular-resolved and obtained from pixel intensities of the image sensor. The special imaging principle enables the usage of low-cost, compact high-power CW laser diodes and highly integrated CMOS/CCD image sensors, which can greatly reduce the system cost as well as the system complexity of an atmospheric lidar system. This work reports the recent achievements in the development and applications of the Scheimpflug lidar techniques in atmospheric aerosol studies and pollution source tracking, etc.
