Holographic optical elements having lightguides with multiple hologram recordings and methods of making the same

There are provided holographic optical elements (HOEs) and methods of making the same. An example of such methods includes recording a first hologram in a contiguous holographic recording medium of the HOE. The first hologram may receive a beam of light and direct at least a portion of the beam into...

Zusammenfassung:	There are provided holographic optical elements (HOEs) and methods of making the same. An example of such methods includes recording a first hologram in a contiguous holographic recording medium of the HOE. The first hologram may receive a beam of light and direct at least a portion of the beam into a light guide to form an incoupled beam. The method also includes recording a second hologram in the contiguous holographic recording medium. The second hologram may receive at least a portion of the incoupled beam and direct the portion of the incoupled beam out of the light guide to form an outcoupled beam. In addition, the method includes affixing the holographic recording medium to the light guide.
