Measuring 3D profile and position of a moving object in large measurement range by using tracking fringe pattern

The profile and position of a moving object have been measured by using a tracking fringe pattern. The 3D profile of the object is determined from the distorted fringes, and the absolute coordinate is determined from the angle of the reference-tracking fringes. This method enables us to track a movi...
