可见光被动传感与通信：分类、挑战与机遇
Passive Sensing and Communication Using Visible Light: Taxonomy, Challenges and Opportunities
摘要：
一个多世纪以来，人工照明主要用于照明。直到最近，我们才开始改造我们的照明基础设施，以提供室内定位和网络连接等新服务。这些创新性的进步依赖于两个关键要求：调制光源的能力（用于数据传输）和物体上的光电探测器的存在（用于数据接收）。但不是所有的光都可以被调制，大多数物体都没有光电探测器。为了克服这些限制，研究人员正在开发新的传感和通信方法，这些方法利用太阳等被动光源，并利用物体的外表面，如手指和车顶，以创建基于可见光的新一代网络物理系统。在这篇文章中，我们提出了一个分类来分析这些新的贡献。我们的分类使我们能够确定这个新兴领域的总体原则，挑战和机遇。
英文摘要：
For more than a century, artificial lighting has served mainly for illumination. Only recently, we start to transform our lighting infrastructure to provide new services such as indoor localization and network connectivity. These innovative advancements rely on two key requirements: the ability to modulate light sources (for data transmission) and the presence of photodetectors on objects (for data reception). But not all lights can be modulated and most objects do not have photodetectors. To overcome these limitations, researchers are developing novel sensing and communication methods that exploit passive light sources, such as the sun, and that leverage the external surfaces of objects, such as fingers and car roofs, to create a new generation of cyber-physical systems based on visible light. In this article we propose a taxonomy to analyze these novel contributions. Our taxonomy allows us to identify the overarching principles, challenges and opportunities of this new rising area.
