Holography for the DIY

A holographic process is a process which captures  light waves and wave properties hitting an object and stores these  3-dimensional wave information onto a 2-dimensional media. in such a way that just the wave-information is enough to reconstruct the image of that object. Most people think of holograms as a way to project 3-dimensional pictures having some sort of perspectives. That, as fascinating as it may, is not the only thing makes  holograms absolutely amazing. The fact is that each grain, yes, each grain, in the medium contain enough information to reconstruct a whole pictures. What is the down-side?  The fact is that, the smaller the "cut" the less detailed it is. Yet, each piece is enough to "identify" a whole picture. The implications here are ENORMOUS. I am presently in the process of writing an essay on this subject. As you shall soon see holography will go a long way  to explain so to the most mysterious phenomenon.

Creating a hologram is a very difficult and tedious process. One of the critical thing for making holograms is a REFERENCE laser beam. That beam has to be absolutely steady -- the least disturbance will upset the holographic process. The ground vibrations cause by outside vehicular traffic, for example, is enough to kill the holographic-making process. To ensure a steady platform an expensive optical platform is necessary.  However, leave it to the do-it-yourselvers  of society,  and you they will come up with elegant inexpensive way of doing things.
