Paper Abstract

We present a rapid whole-field, 3-D imaging technique based on low coherence interferometry using photorefractive holography in semi-insulating Multiple Quantum Well (MQW) devices, which is capable of whole-field depth resolved 3-D imaging at frame rates exceeding 475 fps. Photorefractive holography provides a unique mechanism to discriminate against a diffuse light background, making it attractive for imaging through turbid media, e.g. for biomedical applications. We note that this whole-field technique can exploit sources of almost arbitrary spatial coherence, including LED's, fibre-coupled laser diode arrays, broadband c.w. lasers etc, as well as ultrafast laser pulses. The use of spatially incoherent light greatly reduces the deleterious impact of speckle.
