Holographic optical element and manufacturing method thereof, image reconstruction method, and augmented reality glasses |
| abstract |
A holographic optical element and a manufacturing method thereof, an image reconstruction method, and augmented reality glasses. The holographic optical element (1) comprises a substrate (101) and a recording material layer (102). At least two groups of interference fringe are recorded in the recording material layer (102), and each group of interference fringe comprises a first interference fringe and a second interference fringe. The first interference fringe is formed by first signal light (3) and first reference light (5) respectively entering two sides of the recording material layer (102). The second interference fringe is formed by second signal light (4) and second reference light (6) respectively entering the two sides of the recording material layer (102), and the second signal light (4) passes through a lens (2, 2') before entering the two sides of the recording material layer (102). An incident angle of the first signal light (3) is equal to an incident angle of the second reference light (6). Incident directions of the first signal light (3) corresponding to the groups of interference fringe are different from each other, and the focal lengths of the lenses (2, 2') through which the second signal light (4) corresponding to the groups of interference fringe passes before the entering the two sides of the recording material layer (102) are different from each other. The holographic optical element manufactured by means of the above method and used to perform image reconstruction can form an image having multiple depths of field. |
