Recently a THSAMM multipurpose scanning acoustic microscope based onPC is developed. A super high-speed A/D converter card, whose samplingrate is over 1GSPS, as well as a fast pulse generator/signal receivercard are inserted in the PC slots. Functions, including testing,processing and display, are realized by the system software. Theoperation frequency range is 1--100MHz. The A, B, C mode scan can beaccomplished at the same time and the real-time results are displayedon the screen of the PC terminal. When test is over, multi-layer B scanand C scan image can be observed from the obtained data. The 3D imageof the structure inside the testing specimen is established by usingacoustic physics, Marching Cube algorithm and OpenGL techniques.This system is successfully applied in many fields and haspotential applications. Some new useful results have been obtained.
