  • Systems, methods and computer program for measuring the surface contour of an object
    Patent number: 6373963
    Abstract: Systems methods and computer program products are provided for obtaining a three-dimensional data set that is representative of a surface of a three-dimensional object. A grating pattern, having a sinusoidally varying intensity pattern, is projected onto the surface of an object. The projected grating pattern is shifted a number of times and two-dimensional deformed grating images of an area segment of the object surface are captured and stored. A two-dimensional array of optical phase values is then created. Optical phase values in the two-dimensional array are then used to generate a plurality of three-dimensional data points that represent respective points on the surface of the object.
