近来研制成功了一种基于PC机、我们称为“THSAM-M”型的多功能声显微镜。在PC机内插入采样率1GSPS的超高速A/D卡和信号产生和接收卡,利用软件完成信号检测、处理、显示功能。仪器工作频率为1-100MHz;在检测样品时,同时多层显示A、B、C扫描结果、根据声学理论、MarchingCube等值面抽取方法和OpenGL技术完成了三维数据的可视化处理,显示样品的内部三维结构。该系统已成功应用于多个领域样品的测量;获得了多项新的检测结果,显示出广阔应用前景。
Recently developed a PC-based, we call “THSAM-M” type of multi-function sound microscope. In the PC into the sampling rate of 1GSPS ultra-high-speed A / D card and signal generation and receiving card, the use of software to complete the signal detection, processing, display capabilities. The working frequency of the instrument is 1-100MHz. At the same time, the results of A, B and C scan are displayed in multiple layers at the same time. According to the acoustic theory, the MarchingCube isosurface extraction method and the OpenGL technique, the 3D data is visualized and the internal Three-dimensional structure. The system has been successfully applied to a number of areas of sample measurement; obtained a number of new test results, showing broad application prospects.
