“…According to the color dispersion phenomenon of reconstructed information observed from this kind of transmission hologram, which is also a rainbow-type hologram, as reported in Ref. 27, the final hologram has the capability of displaying rainbow images with a much wider vertical angular range than the reflection hologram. Although this multiplex hologram is designed for white-light source reconstruction with a specified viewing ring for the recording wavelength, however, a 3D image can be observed with a moderately wide vertical viewing angle, in which a red image can be observed at the inclination angle of approximately 48.7°, whereas a bright green image appears at 34.2°.…”

“…In order to display a 360°-viewable image for the observers around the disk-type multiplex hologram simultaneously, both the object plane and the recording film plane in the optical system should be rotated at suitable angles with respect to the optical axis. 27,28) In these two kinds of IPDTMHs, both the virtual image and real image can be generated. Generally, for the display condition of virtualimage generation, the object information for both 360°-viewable and normal-viewing-type images is recorded on the lower half of a disk.…”

The fabrication methods and parameter design for both real-image generation and virtual-image display in image-plane disk-type multiplex holography are introduced in this paper. A theoretical model of a disk-type hologram is also presented and is then used in our two-step holographic processes, including the production of a non-image-plane master hologram and optical replication using a single-beam copying system for the production of duplicated holograms. Experimental results are also presented to verify the possibility of mass production using the one-shot holographic display technology described in this study.

“…By shifting the rotational axis of the recording film and also reversing the holographic recording sequence, this kind of hologram can be made to generate real image.

In this letter, the method of direct object-image relationship in normal-view disk-type multiplex holography is adopted for theoretical analysis. The corresponding parameters in hologram fabrication and reconstruction process for both virtual-image and real-image generation are also introduced through numerical simulation and experimental results.OCIS codes: 090. 0090, 090.4220, 090.2870. doi: 10.3788/COL201109.120003. Since the concept of wavefront reconstruction was first presented by Gabor [1] , the holographic technology has become one of the most important branches of optics. In 1962, Denisyuk developed a new type of hologram called reflection hologram [2] . The reconstructed image ray generated from a reflection hologram is monochromatic due to its distinguishing feature of high wavelength selectivity, making it suitable for full-color image display [3,4] . Rainbow hologram, the reconstructed images of which can be demonstrated under white-light illumination, was proposed by Benton in 1969 [5] . Recently, multiplex hologram [6,7] proposed by DeBitetto has been applied into several formats, including planar-type, cylindricaltype [8] , conical-type [9] , and disk-type [10] holograms. Conventional multiplex holograms are composed of a series of long thin individual holograms, which inevitably cause the reconstructed images overlaid with a fence structure [10] . To eliminate the fence structure overlaid on the reconstructed image generated from conventional multiplex hologram, the image-plane method is utilized. The image-plane method has been designed for various formats of holograms, including cylindrical-type, conicaltype, and disk-type holograms [11−13] . Due to the lower diffraction efficiency of multiple-exposure holograms, the two-step recording technique was developed to overcome this limitation [14,15] . Reflection holograms have been widely used for display; thus, we developed reflection image-plane disk-type multiplex hologram (IPDTMH) through both one-step and two-step recordings [16,17] . The disk-type multiplex hologram has the advantage of commercial mass production owing to the utilization of the well-developed CD technology. Recently, we developed a 360-degree-viewable IPDTMH by one-step recording [18] . In the current letter, we describe how to make a normal-view IPDTMH using a one-step process. The 3D-display conditions for virtual-image and realimage generation are discussed. Suitable parameters for holographic recording are obtained by numerical analysis, and experimental results are also demonstrated.The holographic processes for making an IPDTMH are introduced by Figs. 1 and 2. Figure 1 shows our optical system for IPDTMH fabrication by one-step recording while Fig. 2 shows the reconstruction condition for a transmission-type IPDTMH. In the hologram fabrication process, the recording film is illuminated by a normalincidence object beam W O and a reference beam W C . On the holographic film plane, a series of image-plane holograms is recorded. For viewers at the observation plane dur...
