The covariogram gK​ of a convex body K in Ed is the function which associates to each x∈Ed the volume of the intersection of K with K+x. In 1986 G. Matheron conjectured that for d=2 the covariogram gK​ determines K within the class of all planar convex bodies, up to translations and reflections in a point. This problem is equivalent to some problems in stochastic geometry and probability as well as to a particular case of the phase retrieval problem in Fourier analysis. It is also relevant for the inverse problem of determining the atomic structure of a quasicrystal from its X-ray diffraction image. In this paper we confirm Matheron’s conjecture completely.
