You might have seen holograms on your drivers liscense or a CD or a DVD but those aren't very impressive. Larger scaled holograms that use lasers or precisely directed light to illuminate them are far more thrilling. In definition, a holographic technique is used to create 3 dimensional (or 3D) images using light, but what kind of light? Holograms use lasers in order to produce a life like image, these lasers create special light waves that when directed onto the hologram it shows us a 3 dimensional image that's so life like it's like the real thing!

It all starts with light. Light is something that we humans wouldn't be able to live without, as a matter of fact barely anything on Earth would be able to live without it. As humans and as animals we wouldn't be able to see and as plants we wouldn't be able to grow. When you look at something, whether it be a tree or a grain of rice, both of your eyes see different angles of the object. Much like a hologram, when you look at the image using different perspectives you can see the object as it would be if it was actually real. This is because your brain processes this information so that you see the world in 3D. But why is this not possible with photographs? It's because a camera lens can only focus on making the object into a flat 2D image, it doesn't capture all of the waves of light reflected off of these objects.
