title: Spatial coherence modulation.
abstract: The principles of amplitude and phase modulation of the spatial coherence of the optical field are discussed. They are based on the modification of the phase-space diagram of the field, provided by the marginal power spectrum, which allows synthesis of the modulating functions of the spatial coherence and the corresponding complex transmissions to be transferred onto a spatial light modulator for application purposes. Numerical and experimental results are presented. This novel technique can be applied in designing specific shapes of power distributions.
