Abstract:	We have demonstrated a setup using a BaTiO3 crystal which functions as either a color converter or an incoherent-to-coherent converter, depending on whether the input pattern is carried by a coherent or an incoherent beam. There are two beams of light involved in the experiment: a pattern-carrying beam and a pattern-grabbing beam. The setup operates on the principle that the noise gratings formed by the pattern-grabbing beam and its scattered waves in the photorefractive crystal are erased by the input pattern. As a result, the setup behaves as a transmission spatial light modulator, and the output patterns are positive replicas of the input patterns.
