Building on previous EPSRC-funded work on developing novel applications of telescope windows, which are arrays of small telescopes typically formed by pairs of microlens arrays, this project aims to advance such applications further:1. Overcome or avoid problems with prototype devices uncovered by previous work. For example, previous work uncovered an field-of-view limitation of telescope windows used as magnifying or de-magnifying medical spectacles. This project aims to increase the field of view using optical engineering, and to identify situations in which the field-of-view limitations are not relevant.2. Ignoring the shortcomings of current devices, theoretically explore potential applications. For example, idealised telescope windows can be used to construct invisibility cloaks and, more generally, transformation-optics devices which might in future find applications such as medical spectacles that "flow" the view around damaged areas of the retina.3. Develop novel devices that can perform the function of current microlens devices, but better. For example, metasurfaces might be able to change light-ray direction like telescope windows, but without field-of-view limitations.

在之前epsrc资助的开发望远镜窗口新应用的工作基础上，该项目旨在进一步推进此类应用：1。克服或避免先前工作中发现的原型设备问题。例如，先前的研究揭示了用作放大或缩小医疗眼镜的望远镜窗口的视场限制。本项目旨在利用光学工程增加视场，并确定视场限制无关的情况。忽略现有设备的缺点，从理论上探索潜在的应用。例如，理想的望远镜窗口可以用来制造隐形斗篷，更普遍的是，转换光学设备可能在未来的应用中，如医疗眼镜，在视网膜受损区域周围“流动”的视野。开发新的器件，可以执行现有的微透镜器件的功能，但更好。例如，超表面可以像望远镜窗口一样改变光线方向，但没有视野限制。
