Direct-to-video holographic 3-D imaging using photorefractive multiple quantum well devices

Abstract: Customised photorefractive quantum well devices have been developed for real-time video acquisition of coherence-gated, three-dimensional images. Holographic imaging with direct video capture has been demonstrated. The technique has been applied to 3-D imaging through turbid media with 50 µm transverse and 60 µm depth resolution being achieved using near infrared light through a phantom of 13 mean free paths scattering depth. Spectrally-resolved holographic imaging has also been demonstrated. 1998 Optical Society of America OCIS codes: (090.0090) Holography; (110.6880) Three-dimensional image acquisition; (170.1650) Coherence imagin
