Abstract
© 2018 Optical Society of America. Manipulating the propagation of light through scattering media remains a major challenge for many applications, including astronomy, biomedical imaging, and colloidal optics. Light can be focused through inhomogeneous media into any desired point with wavefront shaping techniques. However, scattering correlations, referred to as the optical memory effect, limit spatial range within the scattering medium, where a single wavefront correction remains accurate. Selecting only the weakly scattered light is a promising way to increase this correlation range. Here we investigate spatial scattering correlations by digitally time-gating the early arriving light in the spectral domain. We demonstrate that the range of the translational memory effect for the early arriving light is increased almost fourfold, paving the way for a range of scattering media imaging applications.

Roarke Horstmeyer is an assistant professor within Duke's Biomedical Engineering Department. He develops microscopes, cameras and computer algorithms for a wide range of applications, from forming 3D reconstructions of organisms to detecting neural activity deep within tissue. His areas of interest include optics, signal processing, optimization and neuroscience. Most recently, Dr. Horstmeyer was a guest professor at the University of Erlangen in Germany and an Einstein postdoctoral fellow at Charitè Medical School in Berlin. Prior to his time in Germany, Dr. Horstmeyer earned a PhD from Caltech’s electrical engineering department in 2016, a master of science degree from the MIT Media Lab in 2011, and a bachelors degree in physics and Japanese from Duke University in 2006.
