What is Hologram?

>> Rabu, 03 Juni 2009

Shows how the hologram is a 3-D image. When given the right light, the hologram can create an image of 2-D and 3-D.Hologram was created using a laser ray. Sinar laser split into 2, the first thing would reflection of film and the other on the drive directly to the film without reflection. When the hologram film be in a certain way it will appear 3-dimensional image.

Wave laser is coherent, and has a large wavelength, top and valley are same. Holograms can be created using a laser coz the making need a regular waves, does not like laser rays, light waves are not always uniform, so not useful for this.
