ABSTRACT

In a standard hologram scheme the spatially-coherent radiation with a monochromatically-modulated amplitude should have a “carrier” wave interference pattern, which is to be superimposed by the pattern of the modulating wave. Respectively, image reconstruction may be performed by a frequency-modulating field. The problem is relevant to the case of distant frequencies (carrier and modulating), because the nature of interaction of electromagnetic waves with an object (“optical” properties of a medium) will be entirely different. Example: optical (modulating) and X-ray (carrier) radiation. Here arises another question: may be one can make a scheme with noncoherent carrier wave?
