Abstract
A fiber-optic acoustic array using optic hydrophones wherein sound waves are sensed and displayed as modulated light signals. The light signals so generated are transmitted along the fiber-optic bundles. Many such hydrophones are arranged to form acoustic arrays of increased sensitivity and directionality.
