Paper Abstract

Holographic FLI technique provides a means of reducing fringe clutter noise. Holographic interferometry measures position changes of the order of the wavelength of the light used. Moire techniques provide a means of desensitizing holographic interferometry. Moire techniques may be employed with FLI with the objective of automating the defect detection process. It may be necessary to employ a spatial frequency filtering step to remove fringe clutter noise.
