Antoine Émile Henry Labeyrie (born 12 May 1943) is a French astronomer, who held the Observational astrophysics chair at the Collège de France between 1991 and 2014. He is currently professor emeretus there,[1] and continues to work with the Hypertelescope Lise association, which aims to develop an extremely large astronomical interferometer with spherical geometry that might theoretically show features on Earth-like worlds around other suns, as its president.[2][3] He is a member of the French Academy of Sciences in the Sciences of the Universe (sciences de l'univers) section.[4] Between 1995 and 1999 he was director of the Haute-Provence Observatory.
Labeyrie graduated from the "grande école" SupOptique (École supérieure d'optique). He invented speckle interferometry,[5] and works with astronomical interferometers. Labeyrie concentrated particularly on the use of "diluted optics" beam combination or "densified pupils" of a similar type but larger scale than those Michelson used for measuring the diameters of stars in the 1920s, in contrast to other astronomical interferometer researchers who generally switched to pupil-plane beam combination in the 1980s and 1990s.
The main-belt asteroid 8788 Labeyrie (1978 VP2) is named in honor of Antoine Émile Henry Labeyrie and Catherine Labeyrie.[6] In 2000, he was awarded the The Benjamin Franklin Medal.
