Acousto-Optical Tomography Investigation of Ultrasonic Field

摘要

The proposed research was to apply the principles of computer aid tomography to acousto-optic data for the purpose of investigating sound radiation and scattering. The principal investigator had previously developed the theory and logic but lacked the facilities, namely for computer acquisition, mass storage, display of the large amounts of information involved. The objective of this contract was to allow the principal investigator and colleagues at the Navy Research Laboratory, Washington, DC to implement the necessary hardware and computer algorithms during the semester of 1979. The Physical Acoustics Branch of the Naval Research Laboratory had both the acousto-optic facilities and the on-line computer system. Upon submission of the proposal, the principal investigator sent to the scientific personnel at NRL, the requirements for the manipulation of the acoustic radiating system. The personnel there designed a manipulator and ordered the required parts to build the device. The plan of action was for the principal investigator to become familiar with the computer system while the manipulator was being built.
