1978 OSA President and Honorary Member Emil Wolf, born 30 July 1922, is a Czech-born American physicist who made advancements in physical optics, including diffraction, coherence properties of optical fields, spectroscopy of partially coherent radiation, and the theory of direct scattering and inverse scattering.
Wolf was forced to leave his native Czechoslovakia when the Germans invaded. After brief periods in Italy and France (where he worked for the Czech government in exile), he moved to the United Kingdom. He received his B.Sc. in mathematics and physics in 1945, and a Ph.D. in mathematics from Bristol University, England, in 1948.
Between 1951 and 1954 he worked at the University of Edinburgh with Max Born, writing the famous textbook Principles of Opticsusually known simply as “Born and Wolf”. After a period on the faculty of the University of Manchester, he moved to the U.S. in 1959 to take a position at the University of Rochester. He is currently the Wilson Professor of Optical Physics at the University of Rochester.
In addition to Principles of Optics Wolf has also written, along with Leonard Mandel, Optical Coherence and Quantum Optics, and is the author of Introduction to the Theory of Coherence and Polarization of Light and Selected Works of Emil Wolf with Commentary. Wolf is the editor of Progress in Optics, an ongoing series of volumes of review articles on optics and related subjects. Fifty volumes have been published in this series to date, all under his editorship.
Wolf’s research has focused on coherence and polarization of optical fields. He predicted a new mechanism that produces redshift and blueshift, that is not due to moving sources (Doppler effect), that has subsequently been confirmed experimentally (called the Wolf Effect). He also discovered that two non-Lambertian sources that emit beamed energy, can interact in a way that causes a shift in the spectral lines. The Wolf Effect can produce either redshifts or blueshifts, depending on the observer's point of view, but is redshifted when the observer is head-on.
At the University of Rochester Wolf and his research group investigate theories of coherence and polarization of light and inverse scattering. He has recently found solution to a classic problem in the theory of reconstruction of crystal structure from diffraction experiment; namely the determination of phases of the diffracted beam.
Wolf is the recipient of numerous awards for his scientific contributions. These include OSA’s Frederic Ives Medal and the Max Born Award, the Franklin Institute’s Michelson Medal, and the Italian National Research Council’s Marconi Medal. Wolf is also an honorary member of the Optical Societies of India and Australia and is the recipient of seven honorary degrees from Universities in the Netherlands, Great Britain, Denmark, France, the Czech Republic and Canada.
In 1976, Wolf was elected to the OSA Board and served as President of the Society in 1978. In 1987, he was named an Honorary Member of the Optical Society in recognition of his preeminent service in the advancement of optics.
In 2008, the Emil Wolf Outstanding Student Paper Competition was established to honor Emil Wolf for his many contributions to science and the Optical Society, this competition recognizes the innovation, research and presentation excellence of students presenting their work during Frontiers in Optics (FiO). This program is sponsored by Optics Communications published by Elsevier. Additional support has also been provided by Physical Optics Corporation, the University of Rochester Physics Department, the Institute of Optics
