Abstract:

Applications of holographic interferometry to vibration analysis, composite component evaluation, and precision cylinder inspection are presented. Stroboscopic holography is compared with time-average holography, and typical results are presented. The results of the holographic inspection of molded graphiteepoxy composites and honeycomb panels are reported. A technique for the comparison of the internal radial dimensions and straightness of precision cylinders such as gun barrels is described along with typical results. Author, modified-PL
