[4][2] His work spanned several topics in physical optics, including holography and photogrammetry.
[3] He made important contributions to the development of optical data processing and synthetic holography.
He also spent a year with the proximity fuze group of Johns Hopkins University's Applied Physics Laboratory.
He served as acting director of the Institute from 1975 to 1977[4][5] Although Givens officially retired in 1981 at the mandatory age of 65 (at that time a federal law), he continued to teach for another 22 years,[2][3] and even served as Acting Dean of the University of Rochester's Hajim School of Engineering and Applied Sciences [Wikidata] in 1984-1985.
[2] While very successful in research, Givens said the main object of his career was helping people to learn.
