Abstract

A real time, high-resolution coherence gating system to image through turbid media has been demonstrated. Using the technique of photorefractive holography with Multiple Quantum Well (MQW) devices, high-resolution depth resolved images through 13 MFP have been recorded. The fast response time (less than 0.4 ms) and the high optical quality of the MQW devices allowed images to be acquired, in real-time, direct to a video cassette recorder. The spectral versatility of this system has been demonstrated by recording images at wavelengths from 800 - 850 nm.
