Laser-based systems are one of the most important technologies for remote sensing in environmental applications. This objective aims at the development of a whole system for remote sensing, including the pulsed laser source and the required optics components for beam conditioning. The system will be applied to remote measurement of distance and environmental parameters on a selected target. Technical concepts and laser sources from optical communications systems, including vertical cavity-lasers and pulse shaping, will be used for high resolution measurements. The systems to be developed will be focused on the space-borne remote sensing of the concentration of greenhouse gases like H2S, CO, CO2, NO2, CH4, and C2H4 and distance of a defined atmospheric region. Required adaptive optics based on liquid crystals, including optical vortex generators will be also developed.       

The following activities will be carried out:

Activity 1. Remote active systems for greenhouse gases measurements.

                  Responsible: Ignacio Esquivias (CEMDATIC-UPM)

Activity 2. LIDAR systems for high-resolution distance measurements.

                  Responsible: José Manuel García-Tijero (CEMDATIC-UPM)

Activity 3. Adaptive optics applied to laser beam conformation.

                  Responsible: José Manuel Otón (CEMDATIC-UPM)

Activity 4. Development of laser sources using passive modulators for active sensing.                               Responsible: Fernando Naranjo (GRIFO-UAH)
