The Early Photon Gets the Worm

One of the biggest problems with using light to analyze biological tissue is that photons in the visible and near-visible spectrum have a very high probability of scattering multiple times as they propagate through the tissue. This is a well-known problem that restricts high-resolution optical microscopy to tissue thicknesses of only a few microns. It has also led researchers to develop...
