The transmission and reception optics for a monostatic LIDAR was designed and calibrated at the Universidad del Valle. The system is designed to study the air contamination caused by industrial fumes and aerosols in the low atmosphere of Cali city. The injection system uses a Nd-Yag @532 nm laser beam, which is expanded by a telescopic system and directed by mirrors into the atmosphere, in the direction of the receiving telescope optical axis. The reception optical system is conformed by a lens, which receives the light captured by a Newtonian telescope 6", through a fix opening and a small band interference filter, a second lens focuses the light into an optical fiber which transports the signal to the detector. In this work we present of spectrum of the collected light originating of particles suspended in the low atmosphere, using the basic elastic LIDAR system and spectrometer for their detection.
