Abstract
A method and apparatus is described for contact-free 3 dimensional-measuring of a moving object with periodic motion. The method and apparatus makes use of the projection of a defined intensity pattern onto the moving object and the recording and analysis of a reflected pattern from the object wherein the intensity pattern projection is synchronized to a characteristic periodic frequency period or sub-period of the moving object.
