Abstract

This paper will provide an overview of the initial reflection spectrum experiments conducted to utilize the unique characteristics of the 12-axis dual transducer ultrasonic workstation, which has been designed and fabricated at MSU [1]. This system was designed as an oblique incidence research scanning tool unlike commercially available multi axis machines which are more suited for contour following and high speed scanning. Through the implementation of DSP processors, it has become possible to process and image the ultrasonic data in near real time, using a personal computer such as a 486 PC.
