TEM中多功能相位操纵的前景：超越像差校正
Prospects for versatile phase manipulation in the TEM: beyond aberration correction
摘要：
在本文中，我们探讨的愿望，透射电子显微镜，其中的电子波的相位可以自由控制。我们讨论了不同的现有方法来操纵电子波的相位和它们的局限性。我们展示了如何与目前的技术的帮助下，电子波已经可以被制作成特定类别的波，每个有自己独特的属性。假设一个通用的相位调制设备是可行的，我们探索可能的好处和方法，可以进入存在借用从光光学，其中所谓的空间光调制器提供可编程相位板相当长的一段时间了。我们表明，一个完全可控的相位板建筑上哈拉尔德玫瑰的遗产在像差校正和电子光学一般将打开一个令人兴奋的研究和应用领域。
英文摘要：
In this paper we explore the desirability of a transmission electron microscope in which the phase of the electron wave can be freely controlled. We discuss different existing methods to manipulate the phase of the electron wave and their limitations. We show how with the help of current techniques the electron wave can already be crafted into specific classes of waves each having their own peculiar properties. Assuming a versatile phase modulation device is feasible, we explore possible benefits and methods that could come into existence borrowing from light optics where so-called spatial light modulators provide programmable phase plates for quite some time now. We demonstrate that a fully controllable phase plate building on Harald Rose's legacy in aberration correction and electron optics in general would open an exciting field of research and applications.
