We demonstrate, both theoretically and experimentally, that a disk-type multiplex hologram can be fabricated as an image-plane hologram that is suitable for white-light line-source reconstruction. By adopting the method of direct object-image relationship, we build the theory based on the imaging property of lenses and on coordinate transformation. Numerical simulation shows the characteristics of this type of hologram. Experimental results reveal that the picket-fence effect that is encountered in the traditional multiplex hologram for images viewed at various distances has been eliminated. Using a reconstruction white-light line source of sufficient length, we observed an achromatic three-dimensional image.
