Exposure Synchronization in Optical Camera Communications for Time Division Multiplexing

IEEE Photonics Journal, 2023
Optical camera communication (OCC) is a type of visible light communication that employs a camera as the receiver. Various flicker-free OCC methods using a general-purpose low-frame rate camera have been proposed.

Cryptic Ontogenetic Changes in the Ventral Coloration of a Color Polymorphic Wall Lizard (Podarcis muralis)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 1, Page 39-57, January 2026.
Wall lizards' ventral coloration undergoes cryptic ontogenetic color changes invisible without UV vision. We tracked wall lizards from hatching to one year of age. Spectrophotometry and visual modeling reveal that juveniles show a distinct UV‐enhanced white coloration that changes differently across sexes and body regions.

MAC Protocol Design for Optical Wireless Body‐Area Networks: Latency, Energy Efficiency and Scalability Analysis

IET Networks, Volume 15, Issue 1, January/December 2026.
This work investigates suitable MAC protocols for medical optical wireless body‐area networks (WBANs), focussing on multiple access management. Using realistic channel models, we evaluate the network performance in terms of energy efficiency, quality‐of‐service and scalability for different IEEE protocols, for both intra‐ and extra‐WBAN connectivity in
