About

Xiaoyuan Liu is a leading researcher in the field of meta-optics, with a primary focus on advancing meta-lens technology for next-generation imaging and depth-sensing systems. Dr. Liu’s major contributions lie in pushing meta-lens capabilities from simple two-dimensional imaging to sophisticated three-dimensional edge detection and depth perception. Notably, Liu demonstrated a groundbreaking light-field edge detection system using a gallium nitride achromatic meta-lens array, enabling edge detection across one to three dimensions (59 citations). This work was further extended to binocular meta-lenses for enhanced depth perception, a crucial development for spatial computing and virtual reality applications (64 citations). Liu also pioneered the "Meta-Lens in the Sky" concept, showcasing a polarization-independent meta-lens camera that leverages the flat, lightweight, and customizable advantages of meta-optics for practical, real-world deployment (26 citations). With a growing citation impact, Dr. Liu’s research is at the forefront of making portable, accurate, and compact optical systems a reality, directly addressing the demands of the metaverse and advanced imaging technologies.
