The hologram, a product of Holographic imaging had been introduced in the sci-fi futuristic movie classic, Star Wars. Princess Leia appeared in the 3-dimensional holographic image as she made her plea in the movie, 'Help Me, Obi Wan!'. That concept was brought into the real world by playing around with light to project real-life holograms not only for objects, humans, animals, among others.

This 3 - Dimensional Holographic imaging that is almost near to projecting real-life reality is the center of the research conducted by several researchers. Scientists at the MIT Media Lab led by Michael Bove had conducted an experiment of the hologram of Princess Leia through holographic projection by using the camera sensor of the Kinect gesture-recognition system according to Blastr.

The team did the experiment with the use of only a 16 low-resolution infrared camera distributed evenly on a one meter long line. The images were then processed in the computer to be inputted into the 3-D holographic projector at 15 frames per second. In their very recent work, they employ structured light thru projecting a grid laser into the scene to produce a 640 X 480 pixels resolution hologram.

Likewise, physicists at the Australian National University created a small device with nanotechnology using micro silicon materials. In a report by Livescience, this invention is capable of creating light-based 3-D Holographic projections. Very tiny silicon strips, which are 500 times thinner than the human hair serves as the pixel projector.

In Holographic imaging, all the information, space and time makes up the 3-D reality that are put together in a 2-dimensional surface. Therefore, in the Holographic 3-Dimensional state, the image that is projected is real as if it can be seen, touched, felt and experienced.
