Design and analysis of single-layer f-θ metalens enabling wide-field-of-view, low-distortion scanning
F-θ scanning lenses represent a critical component in laser systems for high-end intelligent manufacturing and optoelectronic applications, as they directly govern the system’s positioning accuracy, imaging resolution, and processing quality. In this work, we propose an ultra-thin (0.625 mm) single-sided monolithic f-θ...
