(54) THREE-DIMENSIONAL IMAGE PROJECTOR


(57) An object of the present invention is to display a highly reproducible three-dimensional image in response to changes in the viewer's position and to easily realize the miniaturization of the system. The three-dimensional image projector 1 includes a projection image forming disc 4 in which a hologram recording medium 9 is formed along a disc-shaped glass substrate 8a, and which projects image light having directivity by causing the image light to fall incident on the hologram recording medium 9, and a rotational drive unit 3 for rotationally driving the projection image forming disc 4 along a surface of the glass substrate 8a with the center point C1 on the surface as a rotation center. The projection image forming disc 4 is preliminarily recorded with a hologram 11 by causing two laser beams L2, L3 as reference light and object light to simultaneously fall incident on the hologram recording medium 9.
