ABSTRACT:
The present invention relates to holographic lenses.
The wide field holographic lens in accordance with the invention is obtained by the superimposition of interference networks recorded within the volume of a thick material. These networks constitute a corresponding number of thick elementary holographic lenses, each of which satisfactorily covers a specific region of the field; the invention likewise describes a device for constructing said wide field holographic lens.
