Abstract
An improvement to the above described techniques for producing a holographic stereogram. The present invention uses a hologram lens in the process of creating the holographic stereogram, and also uses Fourier transforms of the images for projection onto the recording medium, not the images themselves. A lens between the generated images and the recording medium performs the inverse Fourier transform to convert the image back into a normal image.
