Abstract:
1. A holography device, comprising: a light reaction layer configured to react with light so as to form and remove a diffraction grating; a metal thin film on the light reaction layer; a buffer layer configured to prevent deformation of the light reaction layer from affecting the metal thin film, and configured to be an exterior of the light reaction layer; and a prism or prism array on the metal thin film; wherein when first light is incident on the metal thin film while the diffraction grating is formed in the light reaction layer, surface plasmon formed on the metal thin film is diffracted so as to output a holography image, wherein a surface of the buffer layer, which contacts the light reaction layer, is deformed to have a complementary shape to a deformation of the light reaction layer, but an opposite surface of the buffer layer is not deformed, and wherein the prism or prism array is configured to adjust an inclination angle of the first light.
