Abstract : This report describes the development of a programmable data-retrieval system for in-plane displacements form speckle photographs. The system can produce a whole field printout of in-plane displacements. The field size and interrogation density are user selectable. The overall system accuracy is + or -, and the interrogation rate is 0.1 points per second.
