The photorefractive effect is a phenomenon in which the refractive index changes at the
interference fringe, forming a diffraction grating (hologram). Photorefractive materials are …

Coaxial-and counter-optical setups for laser ultrasonics using a photorefractive liquid crystal
were fabricated. In laser ultrasonics, an object is irradiated with a laser pulse to create an …

In this paper, we review recent progress of research on the photorefractive effect of
ferroelectric liquid crystals. The photorefractive effect is a phenomenon that forms a dynamic …

In this paper we present experimental results of study of liquid crystal panels (LCP)
designed for dynamic holography, with new photoconducting and photorefractive elements …

▪ Abstract A review of the field of photorefractive liquid crystals is presented. The first reports
of photorefractive liquid crystals occurred in 1994, and the performance of these materials …

In this chapter the main features of photorefractivity in liquid crystals are reviewed. Both
experimental results and theoretical models are discussed, pointing out the complexity of the …
