In previous years we developed fabrication technologies of nanometric structures having high aspect ratios for producing hard x-ray phase gratings of 200 and 400 nm periods. This year we continue to enlarge area of the gratings and develop more reliable metallization processes which are necessary for medical x-ray energies. We also developed a prototype x-ray lens out of polymer material with a novel fabrication method. Micro and nano fabrication development is costly in nature, but enables new ways to do x-ray imaging that would not have been possible without them.

在过去的几年中，我们开发了具有高纵横比的纳米结构的制造技术，用于生产200和400 nm周期的硬X射线相位光栅。今年，我们继续扩大光栅的面积，并开发更可靠的金属化工艺，这是医疗X射线能量所必需的。我们还开发了一个原型的X射线透镜的聚合物材料与一种新的制造方法。微米和纳米制造的发展本质上是昂贵的，但能够实现新的方法来进行X射线成像，如果没有它们，这是不可能的。
