Recent advances in laser metrology, based on the concept of projection matrices have to led to the development of a new method for quantitative analysis of holograms and specklegrams. Using this method, all necessary calculations can be carried out, in an interactive manner, on a hand held calculator. In this study, the HP4lC System was used, however, the existing programs can be modified to accomodate other hand held calculators. The parameters required to solve the governing equations of this method are determined directly from multiple observations of holograms, or specklegrams. The results, based on these parameters, provide complete three-dimmensional information on object's translations and rotations, including compensation for rigid-body motions, if necessary, as well as the information on object's deformations. The accuracy of the results obtained in these analysis will be discussed. Representative examples on the use of this method in engineering applications, will be presented.
