Adjustment and alignment of Mie-scattering lidar system

To study the influence of the system optical parameters on the received signal,the profile of signal-to-range under several parameters were given after simulation.It turned out that the laser facula must be adjusted to be smaller than 25mm.Aiming at an object 1000m away,when the error of the angle between the transmitter and receiver axes was 2.2μrad,the emission angle was included in the received field of view of the telescope.
