We describe a coherence-based imaging technique based on degenerate four-wave mixing in two materials. First, a 45°-cut BaTiO3 crystal was used as a self-pumped phase conjugator to obtain depthresolved images through a 4 mean-free-path (mfp) scattering media. In addition, an HITC dye-doped K15 liquid-crystal layer was used to provide single-shot image acquisition through a 2 mfp scattering media. This technique can be used to provide instantaneous (single-pulse), depth-resolved, twodimensional images of the internal structure of scattering materials. Potential applications of this technique include subsurface imaging of biomedical tissue and nondestructive evaluation of composite materials. © 1998 Optical Society of America.
