What can be achieved with holography?

“Holography by itself is a somewhat narrow field, but combine it with others and it makes an area big enough to spend a lifetime in,” stated Emmett Leith (1927-2005), the “reinventor” of the holographic process and co-inventor of the 3-D hologram. Proof of this is the fact that holography has provided and continues to provide innumerable applications in a multitude of scientific and technical fields. Moreover, it is one of the “rare” scientific fields that has provided a medium for art. It is difficult, if not impossible, to enumerate all the developments and applications based on holography so the following is a review of just some of them
