摘要
提出了一种新的分辨率能达到 10nm的X射线像面全息术。它采用了两个波带板 ,其中一个用来成像 ,另一个用来产生参考光束 ,能有效地降低对X射线相干性的要求。全息像能被CCD相机记录。此技术也能用在X射线干涉仪上 。
A new method for taking X-ray image holograms with tens nanometer resolution is proposed. It employs two micro-zone-plates, one is for imaging and the other is for producing the reference. The holograms can be recorded in digital form by a charge-coupled device (CCD) camera. The device can also be used as an X-ray interferometer, called double-zone-plate X-ray interferometer.
