Abstract:
1. Method for manufacturing a hologram recording medium that has an arrangement by which different objects are reproduced when observed from different positions, the hologram recording medium manufacturing method comprising: an object preparation step of preparing a plurality of objects, each of the objects being formed as a set of unit light sources positioned in a three-dimensional coordinate system; a recording plane setting step of setting a predetermined recording plane in the three-dimensional coordinate system; a reference light setting step of setting a predetermined reference light in the three-dimensional coordinate system; an observation region setting step of setting a plurality N of observation regions in the three-dimensional coordinate system, each of the observation regions being associated with a respective object such that the respective object is reproduced when observed from the respective observation region; a pattern computation step of computing an interference fringe pattern formed on the recording plane, based on object light components emitted from individual unit light sources of the plurality of objects and the reference light; and a pattern forming step of forming the interference fringe pattern on a physical medium; and wherein the pattern computation step includes performing computations that each takes into account only light components emitted from the individual unit light sources of each of the objects that would reach the respective observation region.
