长期来,生物学家想对活细胞内发生的现象(如疾病是如何破坏细胞的)进行三维观察。然而用目前已有的技术进行这种洞察是不可能的,X射线全息术却提供了解决这个问题的希望。现在,生物学家探索亚微米世界采用两种技术,但两者均有限制。17世纪荷兰首先使用的光学显微镜,其分辨率受可见光光子波长的 For a long time, biologists wanted to make three-dimensional observations of the phenomena that occur in living cells, such as how the disease destroys the cells. However, with the current technology available to make this insight is impossible, X-ray holography has provided the hope to solve this problem. Now, biologists explore two sub-micron world technology, but both are limited. The first optical microscope used in the Netherlands in the 17th century, the resolution of which depends on the wavelength of visible photons
