At the Universidad del Valle, in Cali (Colombia) a monostatic coaxial micro-Lidar system has been built to study the pollutants and aerosol particles existing in the tropospheric shell over the city and originated by human industrial activities. The system construction process included the design, the adjustment and the test of all the system components, especially the optical parts for the transmission of the laser beam and the reception of the scattered photons, including the photon counting system, the storage protocols and the posterior programs for the analysis of the backscattered light. The system uses a diode pumped Solid State Nd-YAG laser (lambda = 532 nm), a telescope Celestron 6”, and a 9 stages RCA931-A PMT. In this work we present the results of calibration and test of optics systems.
