Introduction
Quang My Han Doan is an inventor based in Singapore. He is associated with Emage Vision Pte. Ltd. and has 1 patent listed in the information provided.
Latest Patents
His patent, “System and Method for Inspecting Mold Defects in Wet Ophthalmic Lenses,” describes a system for detecting defects and measuring the geometric dimensions of cosmetic ophthalmic lenses while they are immersed in saline solution. The system uses a camera and segmented visible and infrared LED illumination to capture images under different lighting conditions.
A custom glass cuvette, designed with concave, concentric, spherical surfaces, helps avoid adding optical power to the lens during inspection and positions the lens at the cuvette’s center. A strobe controller coordinates the camera and illumination, while image-processing tools analyze the captured images to determine whether a lens should be accepted or rejected.
Career Highlights
The patent reflects work on automated inspection technology for wet ophthalmic lenses. Its combination of controlled lighting, specialized lens positioning, and image analysis is intended to support defect identification and dimensional measurement.
