Electromagnetic imaging gives us a new sense of vision to "see the invisible". It achieves this due to the ability to see through most optically opaque materials. This is of great interest for several applications such as security screening and non-destructive evaluation of food, materials and structures. However, current limitations of the existing technology prevent the mass adoption of electromagnetic imaging systems, since they are constrained to very specific niche applications, such as security screening at airports using booth-size systems, which are not affordable in other contexts. Low-cost, portable solutions, such as freehand imaging systems pioneered by the fellow, offer a disruptive solution to redefine the future electromagnetic sensing technology. Nevertheless, these systems suffer from long acquisition times and demand a significant hardware complexity that limit their use as portable scanners (coherent computational imaging). Therefore, the future portable millimeter-wave cameras require drastic changes to be a feasible option for use in real-time applications. For that purpose, the vastly understudied framework of incoherent computational imaging, leveraging compressive sensing techniques, will be developed. The ultimate goal of this project is to overcome the previous limitations to deliver the first portable millimeter-wave single-pixel imager offering real-time performance. In addition, this fellowship will form the beginning of an independent research career of the applicant, who will benefit from a thriving research environment and a comprehensive training program. Moreover, he will be mentored by world-class experts, which will guide him through his research and will help him to build a large collaboration network.

电磁成像使我们有一种新的视觉感，可以“看到看不见”。由于能够浏览大多数光学上不透明的材料，因此可以实现这一目标。对于几种应用，例如对食品，材料和结构的安全性筛查和非破坏性评估等多种应用，这引起了极大的兴趣。但是，现有技术的当前局限性阻止了电磁成像系统的大量采用，因为它们被限制在非常具体的利基应用程序上，例如使用展位大小的系统在机场进行的安全筛查，而在其他情况下这些系统是不起作用的。低成本的便携式解决方案，例如由同伴开创的徒手成像系统，为重新定义未来的电磁传感技术提供了破坏性的解决方案。然而，这些系统遭受了长时间的收购时间，并且需要大量的硬件复杂性，以限制其用作便携式扫描仪（相干计算成像）。因此，未来的便携式毫米波摄像头需要重大更改，这是用于实时应用程序的可行选择。为此，将开发出不连贯的计算成像的框架，并利用压缩感测技术。该项目的最终目标是克服先前的限制，以提供第一个便携式毫米波单像素成像器，提供实时性能。此外，该奖学金将构成申请人独立研究职业的开始，他们将从蓬勃发展的研究环境和全面的培训计划中受益。此外，他将受到世界一流的专家的指导，这将指导他通过他的研究，并帮助他建立一个大型的协作网络。
