ABSTRACT:
Techniques for making individual narrow lenticular holograms for a composite drum shaped hologram wherein the vertical and horizontal aspects of an object beam and of an image therein are optically processed independently of each other. A very narrow lenticular hologram is made preferably having a width related to the horizontal resolution element size of the reconstruct image in order to minimize undesirable lines in the reconstructed image. The image is predistorted in the hologram construction step to account for a wavelength change if one exists between construction and reconstruction. A master drum hologram is constructed with ultraviolet light utilizing photoresist holographic detector material, in one specific embodiment.
