Abstract
According to an aspect of an exemplary embodiment, an authentication apparatus for authenticating an object includes an input coupler configured to receive incident light and generate surface plasmons from the incident light; and an output coupler configured to output a speckle pattern based on the surface plasmons.
Claims23
An authentication apparatus for authenticating an object, the authentication apparatus comprising:
- an input coupler configured to receive incident light and generate surface plasmons from the incident light;
- and
- an output coupler configured to output a speckle pattern based on the surface plasmons.
An apparatus comprising:
- an authentication structure configured to authenticate an object,
- wherein the authentication structure comprises:
- an input coupler;
