Next Generation Imaging using Sparse Single-Photon Data

这是一个物理学博士研究项目，研究了单光子成像的多个方面以及量子通信的相关方面。稀疏单光子和三维成像的使用引起了相当大的兴趣，最终可能会利用量子纠缠的效应。这样的发展必然需要单光子探测的快速计时，这将允许在远距离进行有效的、人眼安全的基于飞行时间的深度剖析。量子纠缠效应可以有效地用于关键的利基例子，如亚瑞利成像、波长变形或量子安全成像。成像技术的这些革命性变化代表着功能方面的范式转变，但在开发定制算法以从这些必然稀疏的数据中提取最大信息以及与其他成像平台(例如多光谱和常规视频)数据融合的要求方面，也提出了重大挑战。本博士学位将考察新的成像方法的许多方面，包括使用新的探测器技术、新的光学配置和使用优化的信号处理算法。

This is a PhD research project in Physics, examining a number of aspects of single-photon imaging and related aspects of quantum communication. There is considerable interest in the use of sparse single-photon and three dimensional imaging, which may ultimately use the effects of quantum entanglement. Such developments will necessarily require fast timing of the single-photon detection, which will permit effective, eye-safe time-of-flight based depth profiling at remote distances. The effects of quantum entanglement could be utilised effectively in critical niche examples, such as sub-Rayleigh imaging, wavelength transmutation or quantum secure imaging. These revolutionary changes in imaging technology represent a paradigm shift in terms of functionality, but present a significant challenges in developing bespoke algorithms to extract maximum information from this necessarily sparse data, as well requirements for data fusion with other imaging platforms, for example multispectral and regular video. This PhD will examine a number of aspects if new imaging approaches, including the use of novel detector technologies, new optical configurations and use of optimized signal processing algorithms.
