Hello! I’m Michel Tallon. I work as a researcher at Lyon Observatory, in various areas of high angular resolution astronomy, and more specifically in adaptive optics on giant telescopes, laser guide stars, wavefront sensing, wave propagation and imaging through atmospheric turbulence, and optical interferometry. My current interests focus on algorithms and signal processing in these domains.

Concerning optical interferometry for instance, besides working at developping LITpro fitting software, I led POLCA project (french ANR) on processing of polychromatic interferometric data for astrophysics.

I also built several instruments, such as SPID (Speckle Imaging by Deconvolution), an advanced speckle camera operating at the SAO 6m telescope in Russia. I am currently working on the adaptive optics system of THEMIS solar telescope, which should be soon available for observations, on another system for high contrast imaging at the National Astronomical Research Institute of Thailand, and also for the next improved adaptive optics system for SPHERE at the VLT.
