PROBLEM TO BE SOLVED: To provide an optical device for reproducing three-dimensional lighting images capable of reproducing three-dimensional lighting images of various shapes by using a single light source and a hologram recording member.SOLUTION: An optical device includes a hologram recording member on which a hologram image is recorded, a light source for reproducing the hologram image of the hologram recording member, a first reflecting surface for projecting the hologram image ahead of the hologram recording member by making a light incident from the light source into a rear side of the hologram recording member at a predetermined angle, and a second reflecting surface for generating light distribution by making the light incident from the light source into the rear side of the hologram recording member.SELECTED DRAWING: Figure 1 |
