Korean Research Team Develops Light-Tunable Polarization Sensor Array to Enhance Autonomous Driving Perception

A research team led by Professor Joonki Suh from the Department of Chemical and Biomolecular Engineering at the Korea Advanced Institute of Science and Technology (KAIST) has developed a self-reconfigurable polarization sensor array. Leveraging the polarization properties of light waves, this technology can automatically adjust its operating state according to the environment to identify the optimal working mode. The sensor effectively distinguishes between water puddles and asphalt roads in dark conditions, addressing a longstanding recognition challenge for conventional vision systems in such scenarios. The findings have been published in the journal *Nature Sensors*.
