ABSTRACT:
Arrangements are made to enable different original images to be reproduced upon observation from different positions and yet enable reproduced images of high resolution to be obtained. In a case of recording two original images, each of the two original images Ia and Ib is defined as a set of point light sources in an XYZ global coordinate system, and two propagation spaces Sa and Sb, each enabling propagation of light emitted from an origin Q of an αβγ local coordinate system, are defined. A predetermined recording plane and a reference light are set in the XYZ coordinate system, and an interference fringe pattern, which is formed on the recording plane by object light components from the point light sources constituting the respective original images and the reference light, is determined by computation. In this process, the computation is performed upon deeming that a light from a point light source belonging to the original image Ia spreads only within the propagation space Sa, with the origin Q of the αβγ coordinate system being overlappingly set at the position of the point light source, and that a light from a point light source belonging to the original image Ib spreads only within the propagation space Sb, with the origin Q of the αβγ coordinate system being overlappingly set at the position of the point light source.
