California Institute of Technology, Ecole Polytechnique Federale de Lausanne, and MIT researchers have developed a technique that counteracts the scattering of light and removes the distortion it creates in images.

The “turbidity suppression by optical phase conjugation” (TSOPC) techniques used a holographic crystal to record the scattered light pattern emerging from a 0.46-mm-thick piece of chicken breast. They then holographically played the pattern back through the tissue section to recover the original light beam.
