Photonic metasurfaces are nano-structured films that can be designed to exhibit tailored light scattering. The phase, amplitude, polarisation and propagation of direction of the reflected and transmitted light can be controlled virtually at will. When used to record holographic information, photonic metasurfaces present many advantages over standard computer-generated holographic devices, mostly related to their ultrathin form factor (a thousand times thinner than conventional diffraction optical elements) and subwavelength dimension of the pixels. Moreover, holographic metasurfaces can be realised in flexible and conformable substrates, which makes them the ideal platform for out of the lab implementation. Ceres Holographics is a leading company in holographic solutions for automotive applications and in this project has partnered with the groups of Synthetic Optics and Organic Semiconductors to take the metasurface technology one step closer to industrial, real-world applications. The aim of the project is to develop a viable and sustainable design and manufacturing pathway for flexible holographic metasurfaces for augmented vision applications. The student will learn how to design holographic metasurfaces for non-flat shapes and develop a scalable fabrication technique based on nanolithography and nanoimprinting. Additionally, the student will exploit the unique properties of metasurfaces to embed sensing capabilities, so that the holographic imaging would depend on specific environmental conditions. This work will be complemented by an extensive experimental activity and completed exploiting the facilities available in the School of Physics and Astronomy of the University of St Andrews and at Ceres Holographics.

光子跨面是纳米结构的膜，可设计用于量身定制的光散射。几乎可以随意控制反射光和传输光的方向的相位，幅度，极化和传播。当用于记录全息信息时，光子元信息比标准计算机生成的全息设备具有许多优势，这主要与其超薄外形（比常规衍射光学元素薄）和像素的亚波长度相关。此外，可以在灵活且合格的基材中实现全息元信息，这使它们成为实验室实施的理想平台。 CERES全息图是用于汽车应用全息解决方案的领先公司，在该项目中，已与合成光学器件和有机半导体组合作，将Metasurface Technology带入更接近工业，现实世界中的应用。该项目的目的是为灵活的全息元信息开发可行，可持续的设计和制造途径，以增强视力应用。学生将学习如何设计用于非平板形状的全息元信息，并根据纳米光刻和纳米印刷开发可扩展的制造技术。此外，学生将利用元信息的独特特性到嵌入感测功能，以便全息成像取决于特定的环境条件。这项工作将通过广泛的实验活动进行补充，并完成了圣安德鲁斯大学物理与天文学学院以及CERES全息图中可用的设施。
