Embodiment Construction

[0172] first working example

[0173] Referring first to FIGS. 1 to 3, there is shown a three-dimensional image display apparatus according to a first working example of the present invention, which corresponds to the first and fourth embodiments of the present invention. This three-dimensional image display device is configured as a monochrome display type three-dimensional image display device. It should be noted that in the following description, the optical axis of the three-dimensional display device is defined as a z-axis, and the coordinate axes of a rectangular coordinate system in a plane perpendicular to the z-axis are defined as an x-axis and a y-axis. Also, a direction parallel to the x-axis is defined as an X direction, and a direction parallel to the y-axis is defined as a Y direction. The X direction is, for example, the horizontal direction of the three-dimensional image display device, and the Y direction is, for example, the vertical direction of the three-d...

Abstract

Disclosed herein is a three-dimensional image display apparatus includes a light source, a light modulation section modulates light from the light source by means of pixels to produce two-dimensional images and emits a spatial frequency of the produced two-dimensional images along diffraction angles corresponding to a plurality of diffraction orders produced from each pixel, a Fourier transform image formation section Fourier transforms the spatial frequency of the two-dimensional images emitted from the light modulation section to produce Fourier transform images whose number corresponds to the number of diffraction orders, a Fourier transform image selection section selects one of the Fourier transform images produced by the Fourier transform section which corresponds to a desired diffraction order, a conjugate image formation section forms a conjugate image of the Fourier transform image selected by the Fourier transform image selection section.
