LAST is designed to simulate the behavior of the atmospheric echoes, by replicating the large dynamic range of LIDAR signals.
This will give the opportunity to test:
– the linearity of the acquisition unit
– sensors response at different wavelenght and luminous power regime
– the response of all optical and electronic elements of a LIDAR system even in case of a multi-layer aerosol distribution
– the presence of crosstalk between the detected channels
The chosen wavelengths are common to more than 95% of the actual worldwide used LIDAR systems.
LAST is as light as possible to avoid any disturbance to the optical alignment of the tested LIDAR.
LAST is compact since LIDAR receiver usually ranges between 150mm and 350 mm.
LAST is portable to test LIDARS on the field; it is also a battery-powered standalone device
