Lille Optical Metrology (MéOL)
Platform
The MéOL platform is a national center of expertise in the field of optical and laser metrology applied to fluid mechanics, combustion and atmospheric physicochemistry. Our expertise covers scientific fields ranging from the study of complex flows and turbulence phenomena in wind tunnels and turbomachinery to the physico-chemical analysis of indoor/outdoor air and combustion processes. We are open to all academic and industrial collaborations and propose services in line with our expertise.
