Abstract
The parallel pixel acquisition inherent in wide-field coherence-gated imaging techniques offers the possibility of high-frame-rate imaging and volumetric imaging, including through scattering media. We discuss photorefractive holography using sensitive, dynamic photorefractive multiple quantum well (PRQW) films as a promising approach and, after reviewing the factors that determine the sensitivity of this technique, we demonstrate that high-frame-rate wide-field coherence gated imaging is possible at 830 frames per second with PRQW devices using a non-intensified camera to record the diffracted signal.
