Paper Abstract

A holographic non-destructive evaluation (HNDE) system with on-line acquisition and processing of real-time interferograms is presented. The system comprises photoconductor-thermoplastic recording materials, an image acquisiton system based on a photodiode-array line scanner. A microprocessor for controlling acquisition and other system functions and a link to a large computer. The system is capable of fringe detection down to an accuracy of 1/100th of a fringe. Applications for the non-destructive evaluation of an actual industrial specimen, as well as mapping the derivatives of deformation of a 2-D object are presented.
