Intelligent Operator‐Independent Flexibility in Robotic Non‐Destructive Evaluation
Advanced Intelligent Systems, EarlyView.Non‐destructive evaluation of high‐value components remains a manufacturing bottleneck due to rigid robotic calibration and fixturing. This study presents a flexible, adaptable system integrating 3D vision and force‐position control with a collaborative KUKA LBR robot. The geometry‐agnostic system enables pose‐independent ultrasonic inspection, detects

Metalens‐Enabled Twisted Chromatic Dispersion
Advanced Physics Research, EarlyView.We successfully demonstrate visible broadband twisted dispersion metalenses. As a proof of concept, we realized two distinct devices: the conical helical and the spring‐like dispersion‐controlled metalenses. These results rigorously validate the universality of our approach in customizing arbitrary continuous 3D dispersion trajectories, thereby ...

Lateral shearing interferometry for high-NA EUV wavefront metrology [PDF]
, 2018 We present a lateral shearing interferometer suitable for high-NA EUV wavefront metrology. In this interferometer, a geometric model is used to accurately characterize and predict systematic errors that come from performing interferometry at high NA ...
