Visible Light communication Laboratory
The Visible Light Laboratory focuses on the research and development of visible light communication (VLC) and positioning technology, with the aim of using visible light as a medium of information transmission to promote innovation in modern communication and positioning systems. With the increasing demand of society for high-speed and efficient communication, traditional wireless technology faces problems such as spectrum congestion and signal interference, and visible light communication, as an emerging technology, shows great potential, especially in the indoor environment has unique advantages.
The laboratory is equipped with advanced optical equipment, laser light sources and highly sensitive sensors to support a variety of experiments and research projects. Our research interests cover optical modulation technology, signal processing algorithms, optical communication network design, light source selection and indoor positioning system development. By studying optical signals of different wavelengths and modulations in depth, we strive to achieve high bandwidth, low latency data transmission, while ensuring system stability and reliability. We also explored a variety of optical modulation techniques, such as pulse width modulation (PWM), orthogonal frequency division multiplexing (OFDM), etc., to improve data transmission efficiency.
In terms of positioning technology, we develop visible-based positioning systems that can provide high-precision location services for smart home, Internet of Things, intelligent transportation and medical monitoring. Compared with traditional GPS systems, optical positioning technology performs better in indoor environments and can overcome the problem of weak or unavailable satellite signals. Our research also includes optimization of positioning algorithms under different lighting conditions to ensure efficient positioning in a variety of environments.
In addition, the laboratory actively cooperates with the industry to promote the practical application of research results, and participates in the formulation of technical standards and industry promotion. We regularly hold academic exchanges and technical seminars, inviting domestic and foreign experts and scholars to share the latest research results and technology trends, and promote interdisciplinary cooperation. Through these activities, we hope to inspire innovation, promote the wide application of visible light technology, and improve people’s quality of life and work efficiency.
Our goal is to provide a solid foundation for future communication and positioning solutions, and to promote the continuous progress and development of visible light technology. We look forward to working with domestic and foreign research institutions and enterprises to jointly explore the infinite possibilities of visible light technology and create a smarter and more efficient future.
