Latest Patents
Wei Wang holds a patent for a "Method and apparatus for measuring small displacement." This invention allows for the detection of small displacements and three-dimensional shapes of objects without the use of an interferometer. The method achieves high accuracy by calculating pseudo-phase information from a speckle pattern that has a spatially random structure. The process involves obtaining a speckle image of the test object before displacement, calculating a spatial frequency spectrum through an N-dimensional Fourier transform, and obtaining a complex analytic signal. The displacement magnitude is determined by comparing the cross-correlation peaks before and after the displacement.
