Cascaded metasurfaces for adaptive aberration correction
简介:Aberration-corrected focus scanning is crucial for high-precision optics,but the conventional optical systems rely on bulky and complicated dynamic correctors.Recently,Shiyi Xiao's group proposed a method using two rotating cascaded trans-missive metasurfaces for adaptive aberration correction in focus scanning.The optimized phase profiles enable precise control of the focal position for scanning custom-curved surfaces.This concept was experimentally validated by two all-silicon meta-devices in the terahertz regime,paving the way for high-precision and compact optical devices in various applications.展开
