Abstract: Hologram data is generated by dividing hologram data generation area, in which hologram data is generated, into a plurality of element sub-areas, computing base hologram data that pertains to an area smaller than the hologram data generation area and that is to form an optical wavefront of an image to be reconstructed, and assigning, as hologram data of the element sub-areas4, hologram data of an entirety or a part of the area to which the base hologram data pertains. Consequently, the amount of operations for generating a hologram pattern in holographic display is reduced.

Abstract: There is provided a practically useful display method that allows viewers to see in-focus images easily. The method includes the steps of providing a lens array including a plurality of lenses, providing display areas at least one of which corresponds to each of the plurality of lenses, displaying partial images of an original image in the display areas respectively, the partial images being different from one another but partially including a same image portion, forming a bundle of beams by beams respectively emergent from the plurality of lenses equivalently, forming virtual images of the respective partial images displayed in the respective display areas by the respective lenses, and forming a single virtual image by superposing the virtual images of the partial images displayed in the respective corresponding display areas formed by the plurality of lenses.

Abstract: A display apparatus includes a spatial phase modulator that forms a display light beam, a transparent substrate in which the display light beam propagates by repeated internal reflection, a bifurcation that emits a portion of the display light beam outside the transparent substrate each time the display light beam undergoes the internal reflection, and a light beam introduction optical system including a beam splitter that guides an illumination light beam to the spatial phase modulator and guides the display light beam formed by the spatial phase modulator to the transparent substrate. The spatial phase modulator forms the display light beam holographically by diffraction of the illumination light beam.
