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.

拟议的研究旨在在女王大学阿拉姆博士的研究团队和 Doric Lenses 之间建立新的研究伙伴关系。此次合作将重点研究利用超表面来提高光学镜头性能的可行性。 镜头无法将不同颜色的光聚焦在同一点（这种现象称为色差）是传统镜头的主要限制。目前，采用多个透镜的组合来减轻色差，但这种组合体积大、价格昂贵并且需要精确对准。超表面是一项新兴技术，它利用平面纳米结构的组合来实现对光流前所未有的控制。该项目的目的是研究使用超表面来提高镜头性能，特别是减少色差的可行性。该项目的成果将导致未来与 Doric Lenses 合作，实施性能更高、成本更低的新一代镜头。它还将为女王大学的博士生提供极好的培训机会。
