Abstract

A holography device may include a light reaction layer configured to react with light to form and remove a diffraction grating, and a metal thin film on the light reaction layer. When first light is incident on the metal thin film while the grating is formed in the light reaction layer, surface plasmon formed on the metal thin film may be diffracted so as to output a holography image. A method of processing a holography image may include recording the image on a holography device by irradiating first light to a light reaction layer to form a diffraction grating, outputting the image by irradiating second light to a metal thin film on the light reaction layer to diffract surface plasmon formed on the metal thin film, and deleting the image from the holography device by irradiating third light to the light reaction layer to remove the grating.
