“…From the viewpoint of diffraction, the cell size should be large unless 3-D objects or scenes are placed very close to the hologram. 11,21 The wavefront reconstructed by one subhologram is considered to be the same as that reproduced by a hologram with a finite square aperture. When the subhologram width is D, the finite aperture P ðxÞ on the x-axis is expressed by E Q -T A R G E T ; t e m p : i n t r a l i n k -; e 0 0 1 ; 3 2 6 ; 2 1 9…”

“…A hologram generated by a wavefront printer is useful for static 3-D scene visualization applications 11,12 due to its ability to reproduce the deep focusing range of a 3-D point. However, it is also expected to be useful for fabricating large complex optical elements, such as microsize nonspherical lens arrays, anamorphic lens arrays, and multiple focallength lens arrays, 13 used in precisely designed 3-D displays.…”

Abstract. Several wavefront printers have been recently proposed. Since the printers can record an arbitrary computer-generated wavefront, they are expected to be useful for fabricating complex mirror arrays used in front projection 3-D screens without using real existing optics. We prototyped two transparent reflective screens using our hologram printer in experiments. These screens could compensate for a spherically distorted reference wave caused by a short projection distance to obtain an ideal reference wave. Owing to the use of the wavefrontprinted screen, the 3-D display was simply composed of a normal 2-D projector and a screen without using extra optics. In our binocular system, reflected light rays converged to the left and right eyes of the observer and the crosstalk was less than 8%. In the light field system, the reflected light rays formed a spatially sampled light field and focused a virtual object in a depth range of AE30 mm with a AE13.5-deg viewing angle. By developing wavefront printing technology, a complex optics array may easily be printed by nonprofessionals for optics manufacturing.

“…An original hologram image is then largely projected through a projection lens at a reflection-type HOE screen. This HOE screen was fabricated by wavefront printing technique [14] and behaves as concave mirror to concentrate a projected light to a target observation point. Therefore, an enlarged holographic image is able to be observed with a large visual angle from a target observation point.…”

“…Recently we have proposed a projection-type holographic display in which a holographic image reproduced by electronic-holography system is largely projected on an HOE screen [10]. On this HOE screen, a concavemirror function was implemented as a reflection-type volume hologram by wavefront printing technique [11]- [14] to concentrate the projected light to a target observation point. Therefore, the observer can see the enlarged holographic image with a large visual angle via the transparent HOE screen.…”

Computer-generated hologram based on ray-sampling plane method was newly applied to the projection-type holographic display that consists of the holographic projection and the holographic optical element screen. In the proposed method, geometric deformation characteristic of the holographic image via the display system was mathematically derived and canceled out by the coordinate transformation of ray-sampling condition to avoid the image distortion. In the experiment, holographic image reconstruction with the arbitral depth expression without image distortion could be optically demonstrated.

“…In wavefront printing, the holograms are calculated by a computer, but the algorithm is different from that of holographic fringe printing. Holographic fringe patterns are diffracted and propagated to the recording medium, interfered with by the reference beam, and reflection volume-type holograms can be achieved [18][19][20][21][22][23][24][25][26].…”

Abstract:The synthetic holographic stereogram printing technique can achieve a three-dimensional (3D) display of a scene. The development and research status of the synthetic holographic stereogram printing technique is introduced in this paper. We propose a two-step method, an infinite viewpoint camera method, a single-step Lippmann method, a direct-write digital holography (DWDH) method and an effective perspective images' segmentation and mosaicking (EPISM) method. The synthetic holographic stereogram printing technique is described, including the holographic display with large format, the large field of view with no distortion, the printing efficiency, the color reproduction characteristics, the imaging quality, the diffraction efficiency, the development of a holographic recording medium, the noise reduction, and the frequency response analysis of holographic stereograms.
