About

Ryotaro Kitaoka is a researcher in optical wireless communications, with a focus on visible light communication (VLC) systems for mobile and robotic applications. His work addresses the challenge of enabling reliable, multiple-access, two-way data transmission using low-cost, low-frame-rate CMOS cameras as receivers. In his most cited paper, "Multiple-access capability of LED visible light communication with low-frame-rate CMOS camera for control and data transmission of mobile objects" (2015, 13 citations), Kitaoka experimentally verified a VLC system that allows multiple mobile objects—such as robots—to communicate simultaneously. He developed a novel synchronization algorithm that significantly improves the symbol rate for multiple-access, two-way links, overcoming a key limitation of camera-based VLC. This contribution is critical for advancing practical, low-power optical communication in environments where radio frequency interference is problematic. Kitaoka’s work bridges the gap between theoretical VLC concepts and real-world deployment, demonstrating how off-the-shelf imaging sensors can be repurposed for robust data and control transmission. His research continues to influence the design of intelligent lighting and autonomous systems, offering a scalable path for integrating communication into everyday optical infrastructure.
