苏州大学，教授

Soochow University，Professor

苏州大学光电科学与工程学院教授，主要从事微纳光学与新型显示的理论和基础应用研究，包括3D显示、抬头显示、近眼显示、微纳制造等。乔教授课题组在基于衍射光波导的大尺寸虚实融合车载显示系统的研究中，缓解了传统HUD中视场角、虚像距离与体积的制约，同时，引入偏振体全息光栅于耦入结构，使光学效率提升约5倍，强光下成像更均匀、对比度更高。邀请她来介绍一下这项技术。

Professor Qiao is a faculty member of the School of Optoelectronic Science and Engineering, Soochow University. Her primary research focuses on the theories and basic applications of micro-nano optics and advanced display technologies, covering 3D display, head-up display (HUD), near-eye display, and micro-nano fabrication.

The research group led by Professor Qiao has made significant progress in the development of large-scale virtual-real integrated in-vehicle display systems based on diffractive optical waveguides. Their work has alleviated the inherent trade-off constraints among field of view (FOV), virtual image distance, and device volume that plague traditional HUDs. Meanwhile, by integrating polarization volume holographic gratings into the coupling-in structure, the team has achieved an approximately five-fold increase in optical efficiency, along with more uniform imaging and higher contrast ratios even under strong ambient light conditions.
