叙述了１０～１００ＭＨｚ频段智能化声显微镜的研制工作。声显微镜由声镜、机械部件、电路和微机软硬件组成。由于其工作频率处于早期声显微镜和普通超声之间，无法简单采用已有电路。为此，采用新技术实现了两种电路。并从理论和实验两个方面分析、对比了单脉冲和脉冲调制两种信号源对声镜的激励特性。结果说明，对低频段声显微镜而言，单脉冲方案较佳。其结构简单，成本低，盲区小。应用研究表明，该机适用于多个工业领域，有广阔的应用前景。 Describes the 10 ~ 100MHz band intelligent acoustic microscope development work. Acoustic microscope consists of acoustic mirror, mechanical components, circuits and computer hardware and software components. Due to its operating frequency between the early acoustic microscope and ordinary ultrasound, can not simply use the existing circuit. To this end, using the new technology to achieve two kinds of circuits. And from two aspects of theory and experiment analysis, compared the single pulse and pulse modulation of the two kinds of signal source of the excitation characteristics of the acoustic mirror. The results show that, for low-frequency acoustic microscope, the single pulse solution is better. Its structure is simple, low cost, small blind spot. Applied research shows that the machine is suitable for a number of industrial areas, has broad application prospects.
