title: Interference diagnostics of white-light vortices.
abstract: The principles and the practical conditions for registration of phase singularities, such as optical vortices in the spectral components of white light, are discussed. Interference diagnostics of white light vortices in a polychromatic speckle-field is reported for the first time.
