激光技术继续扩宽生物学显微镜的能力。在芝加哥,齐尼思无线电公司的研究人员从声学全息照片上记录了葱皮的细胞结构,据说,这是第一次用声学显微镜记录细胞结构。在耶鲁大学,一台扫描的激光系统使人们能够观察到嵌入如脑神经细胞的透明 Laser technology continues to widen the power of biological microscopes. In Chicago, researchers at Zenith Radio recorded the cell structure of onion scallops from acoustical holograms, which is said to be the first time that cellular structures were recorded by acoustic microscopy. At Yale University, a scanning laser system enables one to observe the opacity of embedded brain cells
