DIRECT-TO-VIDEO HOLOGRAPHIC READOUT IN QUANTUM-WELLS FOR 3-DIMENSIONAL IMAGING THROUGH TURBID MEDIA

Customized photorefractive quantum-well devices have been developed fo r real-time video acquisition of coherence-gated, three-dimensional im ages in turbid media. Large-field-of-view holographic imaging with dir ect video capture is now possible. We have evaluated the role of inten sity-limited device performance in Fourier-plane and image-plane holog raphy in such devices and, using near-infrared light, have imaged thro ugh turbid phantoms of 13 mean free paths' scattering depth with 50-mu m transverse and 60-mu m depth resolution.
