1109. My Gal, She's a High-Born Lady (Traditional American) - Leroy Troy
Oswald Jozef Leroy is a Belgian mathematician known for his contributions to theoretical acousto-optics. Leroy's biggest achievement was a theoretical study of the interaction of light with two adjacent ultrasonic beams under different conditions in terms of beam shape, frequency content and intensity. Understanding of this phenomenon was very important in the 1970s when new acousto-optic devices were developed that utilized adjacent ultrasonic beams. Such devices were being used in optical modulators, optical scanners, information processing
, optical filtering and frequency-spectrum analysis. Before his contribution only the interaction of light with one ultrasonic beam was understood. Since then, acousto-optic devices have been used in telecommunication and military applications.
