Remote Sensing        INOE

The UV depolarization eye-safe Lidar system detects Mie/Rayleigh backscattering from atmospheric molecules and aerosol particles.

The laser emission wavelength is UV 355 nm (20mJ) and the detection channels are 355 cross and 355 parallel. The laser pulse duration is 3-6 ns (at 1064 nm), repetition rate 20Hz, and the beam diameter between 3-5 mm at fwhm. The dynamic range covers 1-5 km, depending on atmosphere transmission, with 7.5 m spatial resolution. The reception has a 200mm Cassegrain telescope, and the system acquisition is analog and photon counting, with 20 MS/s analog sampling rate and 250 Mhz photon counting count rate.

The output parameters are the backscatter coefficient and the particle depolarization ratio (for 355 nm).
