Quantitative phase imaging and holography allow highly sensitive detection of phase
changes, for example of surface non-uniformities or refractive index (RI) structures in the …

A holographic interferometer that uses two-wave mixing in a photorefractive (Bi_12SiO_20)
crystal under an applied ac field is described. The interferometer uses a repetitive sequence …

We report on a definitive demonstration of a 3D holographic display utilizing a
photorefractive crystal. The resultant holographic image is viewed in real-time over a wide …

This paper provides a tutorial of iterative phase retrieval algorithms based on the Gerchberg–
Saxton (GS) algorithm applied in digital holography. In addition, a novel GS-based algorithm …

A technique is presented by which holograms can be recorded when an object or scene is
scanned with an optically heterodyned Fresnel zone pattern. The experimental setup, based …

We explore theoretically and experimentally how application of an electric field to a
photorefractive crystal affects the recording and the readout of holograms. We consider, for …

First-order diffraction from thin crystals of photorefractive Bi_12SiO_20 and Bi_12TiO_20 is
investigated for application to real-time holographic interferometry. Enhancement of the first …

We present experimental results of one-way coherent imaging through a thin phase-
aberrating medium using a holographic technique with bacteriorhodopsin as a real-time …

The microscopic characterization of the surface defects on large opto-electronics
components is essential to ensure the performance of major equipment. However, existing …

We present a spiral phase filtering system with a large tolerance for edge enhancement of
both phase and amplitude objects in optical microscopy. The method is based on a Fourier 4 …
