Chrono-coherent imaging for medicine

A method for imaging with visible and near-visible light inside media, such as tissues, which have strong light scattering is described. The chrono-coherent imaging (CCI) method is demonstrated for a transmission geometry where an absorbing object is completely hidden from normal visual observation by scattered light. The resultant images are most similar to X-rays, with cumulative transmission showing absorption features and refractive index differences in the media. Laser coherence properties, coherence measurements, the relation of CCI to light-in-flight holography, holographic film properties relevant to CCI, a particular optical setup for CCI, the results of a demonstration experiment imaging an absorbing object hidden by light scattering, and an experiment to estimate the clinical applicability of CCI are discussed.<<ETX>>
