Abstract

Full-field, retroreflective holographic imaging through turbid media was analyzed using a photorefractive polymer composite as a coherence gate. Two-dimensional images of test objects through 6.5 scattering mean-free-paths in real-time were recorded and reconstructed using a four-wave mixing geometry. A 6.3 mW helium neon laser at 633 nm was used to acquire images with a transverse spatial resolution better than 42 μm in a few seconds. It was shown that the application of a 6.6 kV potential across the 110-μm-thick sample produced an applied field strength of 60 V μm-1.
