美国 Sonoscan 公司制成一种激光扫描声显微镜(SLAM)。这种显微镜将声波转换为可观察的图象,从而为内部微细结构的研究提供新的远景。激光扫描声显微镜的原理可比做用音叉在水盆上发出的声音可以观察到一样。声显微镜是使超声波透过样品传至一反射面上,用激光扫描该表面,将其放大了的图象送至字符图象屏幕显示器上作声学和光学的观察,最后借助于光象来识别声象中的特征。 The United States made a Sonoscan Laser Scanning Sound Microscope (SLAM). The microscope converts sound waves into observable images, providing a new perspective for the study of internal fine structures. The principle of a laser scanning acoustic microscope can be compared to the sound made on a basin by a tuning fork. Acoustic microscopy is the transmission of ultrasound through the sample to a reflective surface, the laser scanning the surface, the enlarged image sent to the character image screen display for acoustic and optical observation, and finally by means of light to identify Characteristics of the sound image.
