Over the past decade an important area of optics has developed. Called photon migration, it is concerned with imaging through highly scattering media, especially biological tissue. From a fledgling activity ten years ago, it has evolved into a major research activity. Entire symposia have been dedicated to this subject. Various research groups have developed various approaches. We have worked in this area since its early days. We have concentrated on electronic holography, in which the hologram is made on the detector of a high performance, cooled, CCD camera. We describe some of the ideas we have conceived, our experimental implementation, and the experimental results.
Emmett N. Leith is the Schlumberger Professor of Electrical Engineering at the University of Michigan. He has worked primarily in the areas of holography, information optics and interferometry for over thirty years. Dr. Leith has in recent years worked on developing new methods for imaging through highly scattering media, such as biological tissue. Among his numerous awards are the Ives Medal of the Optical Society of America, the SPIE Gold Medal and the National Medal of Science. He also received the University of Michigan Russel Lecturer Award in 1981.
