We report experimental results that demonstrate for the first time, to our knowledge, more
than 20 holograms stored and recalled with equal diffraction efficiency in photorefractive …

Holographic interferometry is a nondestructive testing technique with a growing number of
industrial applications. Photosensitive plates used for coherent wavefront recording …

The mechanism of the photorefractive grating recording and erasure in electrooptic crystals
is discussed in detail in TAP61. We will thus restrict this section to the presentation of the …

We present a defect-enhancement system capable of detecting submicrometer defects on
opaque periodic structures using real-time holography in photorefractive crystals. We detect …

A bismuth silicon oxide crystal is used in the diffusion regime as a dynamic recording
medium in a real-time holographic interferometer based on anisotropic self-diffraction. This …

Semiconductors as photorefractive materials sensitive to infrared light are among others
advantageous since they have small response times. Typically these time constants are in …

In this paper, we focus on the features of a self-stabilized holographic recording system with
a photorefractive crystal as a vibration optical sensor. With it and the time-average …

We report on the use of phase modulation in two-wave mixing with negative feedback to
record stabilized photorefractive running holograms with arbitrarily fixed phase shift between …

A phase grating is produced in an iron-doped lithium niobate photorefractive crystal by two-
beam holographic configuration. Digital holography is used to investigate the two …

The relatively slow response and erasure time (of the order of 1 sec at milliwatt-power levels
and decreasing with increasing incident power) of highly sensitive photorefractive crystals …
