Abstract

We experimentally demonstrated transmission of spatial phase information recorded in a spatial-light modulator through a single-mode optical fiber using a coherence function shaper and spectral holography with a low coherent light source. A replica of the diffraction pattern of the original kinoform is generated from a spectral hologram when the hologram is read with HeNe lasers. In contrast to a similar coherent imaging technique with ultrashort pulses, the low coherent light suffers less from nonlinear phase modulation because of its low intensity.
