日本日立制作所研制出一种具有干涉显微功能、振动频率为一千兆赫的超声显微镜。由于其工作频率很高(由原有的200兆赫提高到现在的1000兆赫),并具有干涉显微功能,因此,其纵向分辨率达到0.3微米。这种显微镜可望用于辨别金属相半导体器件,以及生物组织内部结构的细微变化。因此,在医学和生物学领域中,可用来直接观察细胞组织的结构和细胞的生长情况,而再也不需要象过去使用电子显微镜和光学显微镜那样,对试样进行干燥或 Japan’s Hitachi has developed a microscope with interference microscopy, the vibration frequency of one gigahertz ultrasound microscope. Due to its high frequency of operation (from the original 200 MHz up to the current 1000 MHz) with interference microscopic features, its vertical resolution reaches 0.3 μm. Such a microscope is expected to be used to identify metal-phase semiconductor devices, as well as subtle changes in the internal structure of biological tissues. Therefore, in the fields of medicine and biology, it can be used to directly observe the structure of cells and the growth of cells, and there is no longer any need to dry the sample or to use an electron microscope or an optical microscope in the past
