Application of metasurface for improving optical lens performance

拟议的研究旨在建立阿拉姆博士在女王大学的研究团队和多利克透镜之间的新的研究伙伴关系。此次合作将重点研究利用超表面改善光学透镜性能的可行性。透镜无法将不同颜色的光聚焦在同一点上，这种现象被称为色差，这是传统透镜的一个主要限制。目前，使用多个透镜的组合来减轻色差，这是笨重的，昂贵的，需要精确对准。超表面是一种新兴的技术，它利用平面纳米结构的组合来实现对光流的前所未有的控制。本课题旨在探讨利用超表面技术提高透镜性能，特别是降低色差的可行性。该项目的结果将导致未来与多利克镜头公司的合作，以实现性能更高、成本更低的新一代镜头。它还将为女王大学的博士生提供一个极好的培训机会。

The proposed research aims at establishing a new research partnership between Dr. Alam's research team at Queen's University and Doric Lenses. The collaboration will focus on investigating the feasibility of using metasurface for improving the performance of optical lens. The failure of a lens' ability to focus light of different colors at the same point - a phenomenon known as chromatic aberration is a major limitation of conventional lenses. Currently a composition of multiple lenses is used to mitigate chromatic aberration, which are bulky, expensive and require precise alignment. Metasurface is an emerging technology which uses a combination of planar nanostructures to achieve unprecedented control on the flow of light. The aim of this project is to investigate the feasibility of using metasurface to improve the performance of lens, especially to reduce chromatic aberration. The result of the project will result in future collaboration with Doric Lenses to implement a new generation of lenses with improved performance and lower cost. It will also provide an excellent training opportunity for a PhD student at Queen's University.
