title: Dimensionality in optical fields and signals.
abstract: The spatial chaos in optical fields that result from diffraction of plane waves by random-phase objects with a larger-than-unity phase dispersion is studied. An analog method for evaluating the dimension of chaos in the field is described, and a real-time measuring device that uses this method is proposed. A new method for evaluating the signal-to-noise ratios in optical signals is also proposed.
