摘要

A hologram manufacturing apparatus and a hologram manufacturing method for manufacturing a hologram optical device by a split exposure method are disclosed. The manufacturing apparatus comprises light shield means (10) having a spatial light modulator having a light transparent area and a light non-transparent area thereof controlled corresponding to an input signal, and drive means (8) for driving the spatial light modulator by supplying the signal to the spatial light modulator. The light shield means is arranged closely to a photosensitive material (7).
