Title: Yu-Jen Su and Optical Inspection Innovation.
Introduction
Yu-Jen Su is an inventor based in Hsinchu, Taiwan. His patent work includes an optical inspection system designed to distinguish circuit defects from patterns caused by surface metallic texture. Su is associated with Gudeng Equipment Co., Ltd.
Latest Patents
Su is named on one patent, titled “Optical Inspection System of Eliminating Image Noise.” The system uses polarized light to illuminate circuits and capture the reflected light through a second polarizer. An operation processor analyzes the resulting image to determine whether the circuits have defects apart from surface metallic texture. This approach aims to reduce image noise associated with the circuits’ metallic surface patterns and support more reliable inspection.
Career Highlights
Su’s documented patent contribution focuses on optical inspection and image analysis for circuit evaluation. His work addresses a practical challenge in detecting defects when surface texture can create misleading patterns in inspection images.
Collaborations
Su is associated with Gudeng Equipment Co., Ltd. His listed coworkers include Che-Wei Chan and Lin-Hsin Tu.
Conclusion
Yu-Jen Su’s patent describes a polarized-light inspection method that helps separate circuit defects from surface-texture patterns, reflecting his contribution to optical inspection technology.
