Jean Pierre Cariou, former researcher at the Theoretical and AppliedOpticsdepartment at Onera (1984 to 2007), has become Director of Research and Development at Leosphere, one of the PME partners of Onera, specializing in the study of the atmosphere using lidar technology: the monitoring of high atmosphere pollution, meteorological measurement of clouds, wind, humidity, improving airport traffic flows, research into climate change, etc
After a publication outlining the application of this technique to a pulsed laser in 2011, ONERA'sTheoretical and AppliedOpticsDepartment implemented it in a lidar and proved that it worked without any degradation of the lidar signal. Before transferring the technology to industry, it must prove that it works at high powers: to date, two 50- Watt continuous lasers have been coherently combined the aim being to achieve two times 500 Watts
Since 2005, the CNRS, via its Photonics and Nanostructure Laboratory (LPN), and ONERA, through part of the Innovation Design in Optics (CIO) team of the Theoretical and AppliedOpticsDepartment, have joined forces and teams, pooling their knowledge to conduct research in nanophotonics and its applications
WindCube, a compact lidar intended to measure wind speed profiles, has benefited from the research done by the theoretical and appliedopticsdepartment at Onera... Thus, the work in the theoretical and appliedopticsdepartment (DOTA) of Onera on more powerful laser sources will be transferred to Leosphere via another SME, Keopsys, which sells it laser sources on partnership terms
The first demonstrations of this principle were performed in ONERA's Onda laboratory (opto-electronic nanomaterials and related devices), from joint work with the Dota (ONERA's Department of Theoretical and AppliedOptics) and the CNRS / LPN (Laboratory of Photonics and Nanostructures). The research was supported with funding from the ANR and ONERA: the Carnot Antares and the Intrepid project
Onera / Department of Theoretical and AppliedOptics. This work has been done by teams from" the Calibration, Instrument Building and Optical Measuring" unit and" the Optical Instrument Design" unit of the Department of Theoretical and AppliedOptics at Onera, in collaboration with the Utinam Institute of the Observatory of Besançon and the DGA / Aeronautical Techniques
