Eyesafe coherent detection wind lidar based on a beam-combined pulsed laser source.
Laurent Lombard,Matthieu Valla,Christophe Planchat,Didier Goular,Béatrice Augère,Pascal Bourdon,Guillaume Canat +6 more
TL;DR: A coherent wind lidar built with two coherently-beam-combined fiber amplifiers that is close to the theoretical optimum in accuracy, range, and integration time is reported on.
Journal ArticleDOI
Performance assessment of a coherent DIAL-Doppler fiber lidar at 1645 nm for remote sensing of methane and wind
Nicolas Cézard,Simon Le Méhauté,Julien Le Gouët,Matthieu Valla,Didier Goular,Didier Fleury,Christophe Planchat,Agnès Dolfi-Bouteyre +7 more
TL;DR: The lidar ability to monitor an industrial methane leak is demonstrated during a field test and the system performance has been assessed for range-resolved (RR) and integrated-path (IP) methane measurements in natural background conditions.
Proceedings ArticleDOI

Agnès Dolfi-Bouteyre,Béatrice Augère,Claudine Besson,Guillaume Canat,Didier Fleury,T. Gaudo,Didier Goular,Laurent Lombard,Christophe Planchat,Matthieu Valla,J.-P. Cariou,O. Petilon,J. Lawson-Daku +12 more
TL;DR: In this article, a pulsed fibre lidar based on 1.5 mum fibre technology has been demonstrated for wake vortex monitoring on airport sites, the wake vortex cores position resolution is plusmn2 m, the error on circulation 10%.
Journal ArticleDOI
High Brightness 1.5 μm Pulsed Fiber Laser for Lidar: From Fibers to Systems
Guillaume Canat,Laurent Lombard,Agnès Dolfi,Matthieu Valla,Christophe Planchat,Béatrice Augère,Pierre Bourdon,V. Jolivet,Claudine Besson,Yves Jaouën,Sylvia Jetschke,Sonia Unger,Johanes Kirchhof,Evguenii Gueorguiev,Christophe Vitre +14 more
TL;DR: In this paper, the authors discuss the designs and performances of narrow-linewidth erbium-ytterbium fiber MOPA for coherent detection lidars and present the first results of pulsed fiber lidar wake vortices detection using a coherent detection laser.
Journal ArticleDOI
Onboard wake vortex localization with a coherent 1.5 µm Doppler LIDAR for aircraft in formation flight configuration
D T Michel,Agnès Dolfi-Bouteyre,Didier Goular,Béatrice Augère,Christophe Planchat,Didier Fleury,Laurent Lombard,Matthieu Valla,Claudine Besson +8 more
TL;DR: An onboard LIght Detection And Ranging (LIDAR) sensor designed to track wake vortex created by aircraft in formation flight is presented and Monte Carlo simulations show that vortex centers could be located within ±0.5 m.
