The 2000 Benjamin Franklin Medal in Engineering presented to Antoine Labeyrie

The Franklin Institute, Philadelphia, Pennsylvania, awarded the 2000 Benjamin Franklin Medal in Engineering to Antoine Labeyrie for the discovery of speckle interferometry which permits large ground-based astronomical telescopes to achieve their full theoretical angular resolution, and for pioneering work in extending Michelsonʹs method for performing long-baseline multi-telescope interferometry to obtain angular resolution on the order to 10−3/s arcsec.
