Abstract

An accurate transmitter-receiver alignment of a lidar system is essential to obtain correct results. At same time, the effective telescope area can influence the lidar returning signal, especially at the low range. In order to solve this problem, a fast and precise automatic alignment and data correction lidar system is presented, based on an emission- detection overlap model and ray tracing method. Using it we can get an aligned and whole range corrected lidar signal. A centering precision of few mrad has been obtained through a dedicated software automatic controlling a gimbals-mounted mirror. In particular the correctness of the center and of its error has been determined. While through the effective telescope area correction, got the atmosphere parameter as low as 60 m from the telescope. This system has been used in single wavelength direct detection mode and in tunable two- wavelength DIAL measurement. They were respectively applied for continuous monitoring of tropospheric aerosols and continuous measurement of the NO₂.
