Abstract
Angular momentum and angle are related by a Fourier transformation.
As a consequence, restricting the angular profile of a light beam
modifies its orbital angular momentum spectrum, giving rise to an
angular uncertainty relation. I will present some of our
experiments on angular diffraction both for classical light beams
and for entangled photon pairs generated by down-conversion.
