WILLIAM H. CARTER
Research physicist, engineer, educator
Senior Member, 70; died 20 March
William H. Carter was a research physicist and electrical engineer known for his work in coherence theory, optics, and the statistical properties of light. He also worked in academia.
As a graduate student in the early 1960s at the University of Texas at Austin, Carter developed one of the first lasers in the state. In the late 1960s, he became a research associate at the University of Rochester in New York, where he investigated the nature of laser light, holography, and digital image processing and analysis. Together with fellow university researcher and physicist Emil Wolf, he discovered the quasi-homogeneous source model, a theory that states fields are generated by a source with different coherence properties. Their discovery paved the way for various practical military and civilian applications, such as laser communications.
In 1971 he joined the U.S. Naval Research Laboratory, in Washington, D.C. Retiring from there in 1993, he went to work for the U.S. National Science Foundation, also in Washington, as program director of its department of Quantum Electronics, Waves, and Beams, retiring from government work for good a year later.
In academia, Carter was an assistant and then associate professorial lecturer in electrical engineering from 1967 to 1969 and 1971 to 1976, respectively, at George Washington University, in Washington, D.C. He was a visiting research fellow from 1976 to 1977 at the University of Reading, England. He was a professor of electrical engineering and graduate school fellow from 1981 to 1982 at the University of Nebraska, Lincoln. He also taught electrical engineering from 1989 to 1995 at Johns Hopkins University, in Baltimore.
Carter received a bachelor’s degree in 1961, a master’s in 1963, and a Ph.D. in 1966, all from the University of Texas at Austin and all in electrical engineering.
