Photothermal nanocomposite glasses for LiDAR antifogging

Abstract

Moisture accumulation on vision devices severely degrades signal by disturbing light transmission, posing a critical challenge for light detection and ranging (LiDAR) operated in foggy and rainy conditions. Photothermal heating has emerged as a promising antifogging strategy because they convert sunlight into localized heat without external power.1 However, most photothermal antifogging approaches have been developed primarily for visible transparency, with limited consideration of the NIR transmission required for LiDAR operation at 905 nm.
