Abstract

This paper describes a curvilinear scanned acoustical holographic device for imaging various internal objects in geological structures. The rapid-scanning system was developed to provide near real-time holography without the stringent requirements of the usual rectilinear scanned systems. The system has the capability of generating a circular scanned hologram in 15 seconds and this could be reduced with the addition of multiple receivers. The acoustic reference beam is simulated electronically with a selectable inclination angle to provide spatial separation of the images.
