Holograms are used in healthcare to make 3D images of organs, helping doctors plan surgeries and diagnose problems. In education, they let students explore topics like ancient ruins or science in a fun interactive way. Entertainment uses holograms for live shows and cool special effects. They are also used in marketing to show products in 3D and in the military to plan strategies.

Holograms work with a laser. A specific type of mirror splits light from a laser into two beams. One beam shines directly onto a piece of photographic film, while the other beam shines on the object and reflects onto the film. These overlapping beams create a pattern of closely spaced lines. The pattern recorded on the film is the hologram.

Hologram technology uses reflection by capturing light from an object and projecting it into 3D images. Lasers create an interference pattern that reflects the objects details. this reflection makes the image appear more realistic and viewable from all angles. It’s how holograms seem to float in space

A hologram is like a 3 dimensional photograph.

Some types of hologram have to be viewed with light from a laser.

The first hologram was created by Dennis Gabor.

Holograms show height, width, and depth.

Holographic media can last for about 50 years.
