Information system and method for providing information using a holographic element

摘要

An information system and a method for providing information in correlation with light that is incident on an eye includes a holographic element disposed in front of the eye and a device capable of recording optical signals which detects light that is incident on the eye via the holographic element. The device capable of recording optical signals detects light which is diffracted by the holographic element before the light impinges on the eye such that the diffracted light does not enter the eye.

主权项

1. An information system for providing information with respect to an eye, the system comprising:
at least a first optical projection device configured to project infrared light into an environment in a field of vision of said eye; at least one camera configured to detect the infrared light reflected back from the environment; a sensor system configured to obtain information from the environment based on triangulation of the infrared light reflected back from the environment; spectacles including a holographic element disposed in front of said eye; and at least a second optical projection device configured to project light via the holographic element into said eye in correlation with the obtained information; wherein the holographic element has light-refracting characteristics at one or more discrete wavelengths along a partial area of a virtual ellipsoid disposed in front of said eye.
