  • Method and system for on-line real-time measuring the surface topography and out-of plane deformation by using phase-shifting shadow moiré method
    Patent number: 10006761
    Abstract: The present invention is directed to a system and method for on-line real-time measuring the surface topography and out-of-plane deformation by using phase-shifting shadow moiré method. Digital Phase-Shifting Shadow Moiré Method is applied to a system, which receives the reflected images from the surface of transparent or non-transparent plate projected under a light beam passing through a grating. Next, by image correction program, the skewed interference fringe pattern is recovered to the image as if the image acquisition equipment is placed normal to the surface. Furthermore, the received images are processed with Phase-Shifting to show the surface topography of the plate.
