Abstract
An apparatus is disclosed for changing the scale of a pattern printed from a total internal reflection hologram into a photosensitive layer, which apparatus includes means for reconstructing an image from said total internal reflection hologram by illuminating said total internal reflection hologram with a scanning beam and means for moving at least one of the hologram and photosensitive layer such that the magnitude of movement of the hologram relative to the photosensitive layer is equal to that of the scanning beam multiplied by the change of scale required and such that if said change of scale is a magnification the direction of said movement of the hologram relative to the photosensitive layer is the same as that of the scanning beam whereas if said change of scale is a demagnification then the direction of said movement of the hologram relative to the photosensitive layer is opposite to that of the scanning beam, and optionally comprising also means for increasing or reducing the convergence or divergence of the scanning beam so that the image reconstructed from said TIR hologram by said scanning beam possesses the change in the scale.
