Abstract

For transillumination imaging of animal tissue, we have developed a technique to suppress the scattering effect in a turbid medium using the time-reversal principle of phase-conjugate light. In biomedical applications of this technique, the effects of absorption variation and the applicable tissue thickness must be clarified. Analysis of experimental data revealed that the scattering suppression capability of the proposed technique is independent of the absorption change of a turbid medium. Results also verified that the applicable thickness of animal tissue can be extended using a light source with greater coherence length.
