Title: Innovations by Yau Y Hung
Introduction
Yau Y Hung is an accomplished inventor based in Rochester, MI (US). She holds a total of 6 patents that showcase her expertise in the field of electronic shearography and nondestructive testing. Her innovative approaches have significantly contributed to advancements in measuring deformation and detecting defects in various objects.
Latest Patents
One of her latest patents involves a nondestructive testing system for diffusely reflective objects. This electronic shearography system can measure deformation and test objects for defects by producing two laterally sheared images. Coherent light is reflected from the object, and rays originating from different points are directed into an image sensor. The arrangement of mirrors simplifies the optical system and enhances its efficiency. This system can also detect leaks in packages by identifying changes in the interference pattern caused by gas leaks.
Another notable patent is a method for measuring displacement between points on a test object. This invention analyzes objects electronically without the need for photographic film. It generates laterally-displaced images that interfere with each other, producing a recordable pattern. The use of birefringent material and polarizers allows for the analysis of strain and deformation rapidly and effectively.
