Article Abstract
Light serves as an efficient information carrier for communication across air, land, and underwater environments due to its diverse propagation behaviors. Here, we establish a complete-mapping mobile all-light communication network that merges wired modes with wireless moving and fixed nodes, utilizing light sources of different wavelengths. To address alignment challenges in mobile bidirectional light transmission, a visual tracking module and a full-duplex light communication module are packaged together and fixed on a three-axis gimbal stabilizer. The transmission control protocol/internet protocol (TCP/IP) scheme facilitates two-way real-time data transmission, while the complete-mapping network architecture enables seamless and balanced data flow among all nodes, ensuring real-time, bidirectional data exchange and failover capabilities. This decentralized network achieves up to 8 Mbps throughput with a delay of 7.93 ms. The fully symmetric, equipotential, and decentralized design holds the potential for developing advanced all-light information processing and computing systems for seamless connectivity across diverse environments.

Because light has different propagation behaviors at different wavelengths, all-light communication that can transmit and receive data regardless of the environment can completely bridge space, air, and underwater applications via different types of light sources for seamless connectivity. Here, we establish a complete-mapping mobile optical communication network that fuses wireless moving white light and fixed infrared light communication nodes. An image identification module and a full-duplex light communication module are packaged together and fixed on a three-axis gimbal stabilizer to address the dynamic optical path alignment challenge for moving vehicles.

However, mobility is still a crucial issue that hinders its application. Here, we integrated visual-tracking features with DUV light communication systems, consequently proposing a mobile deep-ultraviolet light communication (MDUVLC) system under the transmission control protocol/Internet protocol (TCP/IP) scheme.

Swedish Radiation Safety Authority, Stockholm, Sweden.
A novel, car based, measuring system for estimation of general public outdoor exposure to radiofrequency fields (RF) has been developed. The system enables fast, large area, isotropic spectral measurements with a bandwidth covering the frequency range of 30 MHz to 3 GHz. Measurements have shown that complete mapping of a town with 15000 inhabitants and a path length of 115 km is possible to perform within 1 day.
