论文摘要
本文讨论了用于生物医学应用的光学无线系统的基本体系结构。 After summarizing the main applications and reporting their requirements, {we describe the characteristics of the transdermal and in-body optical channels as well as the challenges that they impose in the design of communication systems.} In more detail, we provide three possible architectures for transdermal communications, namely electro-optical (EO) monitoring, opto-electrical (OE), and all-optical (AO) for neural stimulation, which are currently在研究中，尽管对于体内通信，我们提供了纳米级AO（NAO）概念。对于每种体系结构，我们讨论了主要的运营原理，技术推动力和研究方向的开发方向。最后，我们重点介绍了设计信息理论框架的必要性，以分析和设计物理（PHY）和中等访问控制（MAC）层，该框架考虑了渠道的〜特征。
This article discusses the fundamental architectures for optical wireless systems for biomedical applications. After summarizing the main applications and reporting their requirements, {we describe the characteristics of the transdermal and in-body optical channels as well as the challenges that they impose in the design of communication systems.} In more detail, we provide three possible architectures for transdermal communications, namely electro-optical (EO) monitoring, opto-electrical (OE), and all-optical (AO) for neural stimulation, which are currently under investigation, whereas for in-body communications, we provide a nano-scale AO (NAO) concept. For each architecture, we discuss the main operation principles, the technology enablers, and research directions for their development. Finally, we highlight the necessity of designing an information-theoretic framework for the analysis and design of the physical (PHY) and medium access control (MAC) layers, which takes into account the channels'~characteristics.
