Paper Abstract

A real time, high-resolution coherence gating system to image through turbid media has been demonstrated. Using the technique of photorefractive holography with MQW devices, high-resolution depth resolved images through 16 MFP of scattering depth have been recorded. The fast response time and the high optical quality of the MQW devices allowed images to be acquired, in real-time, direct to a video cassette recorder. We also demonstrate the use of sources of low temporal and spatial coherence to record holograms through solid samples. The reduction of speckle noise is discussed.
