O_TEXTBLOCK_TEXT After the hologram is made, the image can be seen by shining a light at the hologram; the image then looks like a three-dimensional copy of the original object. When light shines in exactly the same direction as the original <HL Topic=Reflection.tpc>REFLECTED</HL> beam, the image looks exactly like the original object.
E_QUEST1 How does a hologram look when it is viewed from different angles?
E_QUEST2 Why do credit card companies sometimes use holograms on their credit cards?
E_QUEST3 Do you need a laser to view a hologram? Why or why not?
D_TEXTBLOCK_TEXT A hologram is a three-dimensional image. To create a hologram, the light beam from a <HL Topic=Laser.tpc>LASER</HL> is separated into two beams. One beam illuminates a real object. The other beam is <HL Topic=Reflection.tpc>REFLECTED</HL> by a <HL Topic=Mirror.tpc>MIRROR</HL> onto a photographic plate. The light from the object combines with the <HL Topic=Reflection.tpc>REFLECTED</HL> beam to create a hologram on the photographic plate.
