Technology

Aww, horse. I almost forgot about this blog. ^___^;

Anyway, more on Technology, I came across some Holography. Before now, I didn't think it was possible, but well, It's been done. :3

Holography is the appearance that something is present, even when it has already been removed. It is done by recording light and then reconstructing it at a later time--much like recording sound and then pushing the Play button to hear it again later. Depending on which angle you look at it, the image changes, so it looks 3D.

Here's the copypasta if you wanna see it in more... sophisticated words. ^__^;;

"Though holography is often referred to as 3D photography, this is a misconception. A better analogy is sound recording where the sound field is encoded in such a way that it can later be reproduced. In holography, some of the light scattered from an object or a set of objects falls on the recording medium. A second light beam, known as the reference beam, also illuminates the recording medium, so that interference occurs between the two beams. The resulting light field is an apparently random pattern of varying intensity which is the hologram. It can be shown that if the hologram is illuminated by the original reference beam, a light field is diffracted by the reference beam which is identical to the light field which was scattered by the object or objects. Thus, someone looking into the hologram 'sees' the objects even though it may no longer be present. There are a variety of recording materials which can be used, including photographic film."

If you wanna see a couple of examples of this being used in real life:
