A novel concept for implementing a high-resolution spatial light modulator using a thin slab
of photorefractive LiNbOs crystal is described. This method uses the photovoltaic effect to …

We demonstrate a technique by which the temporal oscillations in the response of a
photorefractive square-law converter, a recently developed high-contrast spatial light …

We demonstrate a new type of optically addressed spatial light modulator. By imaging an
external grating into a photorefractive material, we write holographic gratings without the …

We have demonstrated a setup using a BaTiO 3 crystal which functions as either a color
converter or an incoherent-to-coherent converter, depending on whether the input pattern is …

We theoretically and experimentally study phase contrast using a photorefractive LiNbO_3:
Fe crystal sheet and realize the high-performance phase contrast operation using C-cut …

Enhancement of sensitivity to hologram storage in a LiNbO 3 crystal is reported by using an
accessory photovoltaic LiNbO 3 crystal, highly iron doped and reduced. With an illumination …

High performance spatial light modulators (SLMs) are essential in many optical information
processing and computing applications for converting incoherent images to coherent …

Spatial filtering and hologram formation using coherent and incoherent imaging techniques
are investigated experimentally in photorefractive materials. Spatial filtering involves …
