The objective of this research is to develop a noncontacting system             for the complete dynamic measurement of all six degrees of freedom of           position and attitude of miniature mechanical components.  This                 information is generally not obtainable, yet it is essential in many            new engineering applications.  The system is based on monitoring three          laser beams reflected from a small reflective target on the component.          By utilizing the geometric origin of the beams and the position of the          respective reflections, all six degrees of freedom of position of the           target can be determined.  The research will optimize the geometry of           the lasers, targets, and sensors in order to achieve the best set of            operational parameters while miniaturizing the overall size.  The               necessary hardware and software will be developed to achieve high               frequency real time operation (30 KHz).  The design will be prototyped          and evaluated to determine the operational limitations and                      capabilities.  The main research emphasis will be on system                     development, with applications directed at noncontacting modal                  analysis of structures.  Specifically the incorporation of the                  rotational degrees of freedom into the experimental modal data base             will be examined using the new measurement capability presented by              this system.
