| Abstract: | A new technique for measuring the time history for 3-dimensional displacement of points on the inside surface of an aircraft transparancy during a simulated impact of a bird has been developed. In this method, a measurement datum and two high speed cameras are used. The cameras are positioned perpendilar to each other and contain a commom field of view of insterested. Some examples are discussed. Very accuate results are obtained. |
