Hologram vs. Iridescent — What's the Difference?

A three-dimensional image formed by the interference of light beams from a laser or other coherent light source.

Producing a display of lustrous, rainbowlike colors

The pattern produced on a photosensitive medium that has been exposed by holography and then photographically developed.

Brilliant, lustrous, or colorful in effect or appearance

The photosensitive medium so exposed and so developed. Also called holograph.

(not comparable) Producing a display of lustrous, rainbow-like colors; prismatic.

A three-dimensional image of an object created by holography.

Brilliant, lustrous, or colorful.

A photographic image giving the observer a seemingly three-dimensional view of the represented object. The three-dimensional effect is produced by exposing a photographic recording medium to an interference pattern generated by a coherent beam of light (as from a laser) reflected from the subject, interacting with a beam directly from the source. The full three-dimensional effect requires illumination of the image with coherent light, but less perfect three-dimensional visual effects may also be observed when the hologram is illuminated with white light.

Having colors like the rainbow; exhibiting a play of changeable colors; nacreous; prismatic; as, iridescent glass. See iridescence.

The intermediate photograph (or photographic record) that contains information for reproducing a three-dimensional image by holography

Varying in color when seen in different lights or from different angles;

Having a play of lustrous rainbow-like colors;
