Abstract
A technique for practicing holography in a vibration environment is described and illustrated with examples. Advantages would consist of the ability to examine small areas of large structures at their installed site, ability to examine deformation in a local area of a structure despite large motions of the overall object, ability to practice holography in a vibrating environment, such as an industrial shop, without vibration-isolation equipment, ability to reconstruct holograms with white light rather than laser light and a much lower equipment cost as compared with the usual laboratory holography system.
Disadvantages would include the limited field of view (size of photographic plate), requirement for coating object with retro-reflecting paint for best results, and the inability to conduct real-time studies.
