The ability to observe one entire s

The ability to observe one entire surface of a large test object at one time, rather than in a series of limited views, is one of
the most important benefits of using holography for nondestructive inspection. One entire surface of an 810 mm (32 in.)
diam jet engine fan assembly can be recorded in a single hologram (Fig. 22), considerably facilitating the performance of
a vibrational-mode analysis that alternatively would require transducers placed over the entire assembly.
