Direct-to-video holographic readout in quantum wells for three-dimensional imaging through turbid media

Abstract

Customized photorefractive quantum-well devices have been developed for real-time video acquisition of coherence-gated, three-dimensional images in turbid media. Large-field-of-view holographic imaging with direct video capture is now possible. We have evaluated the role of intensity-limited device performance in Fourier-plane and image-plane holography in such devices and, using near-infrared light, have imaged through turbid phantoms of 13 mean free paths’ scattering depth with $50-\mathit{\mu }\mathrm{m}$ transverse and $60-\mathit{\mu }\mathrm{m}$ depth resolution.
