dc.description.abstractAn omnidirectional hydrophone having an elastic shell which is spheroidal so that the circumference of the shell about different axes changes differentially when the shell is subjected to pressure variations. The differences in circumference are advantageously measured by an optical fiber interferometer having one leg wound about the equatorial circumference of the shell and another leg wound about its meridional circumference. The shell may be an oblate spheroid having the ratio of its major axis to is minor axis greater than about (2-v)!, where v is Poisson's ratio of the shell material, so that the shell narrows along one axis and widens along the other when the shell is subjected to a pressure change.en_US
