Abstract
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 transmissive 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.
