Our research is mostly concentrated on the development of novel
optical techniques for extracting relevant information in two or
three spatial dimensions in highly scattering materials such as
biological tissue. In such materials, light that would travel in a
straight line in clear materials is instead scattered into random
directions. Such scattering causes normal imaging techniques to
fail. Nevertheless absorption is often low and light may travel a
good distance before being absorbed. We must either detect only the
small amount of unscattered light or find ways to obtain useful
information from the highly scattered light. The principles are very
similar for imaging through skin in the body (at distances of
hundreds of microns to millimeters) and imaging through
adverse weather in the atmosphere (at distances of meters to kilometers).

Returning to Chuck's roots in the field of laser radar, we have been investigating the propagation of light in adverse weather, both experimentally and computationally. We can improve the images collected by scanning lidars through better understanding of the scattering properties of the atmosphere.
