Abstract

In the method for producing holograms, a plurality of images displayed on a spatial optical modulating elementis used as the object light. Through a lens arraycomposed of a plurality of lenses disposed corresponding to each of the images, which are included in the object light, and a reducing optical systemandfor reducing the object light emitted from the lens array, the object light is made to irradiate a recording surfacealong with a reference light; thereby interference light between the object light and the reference light is recorded on the recording surface. Between the spatial optical modulating elementand the lens array, partitionsfor separating the respective images are provided; thereby noise is reduced.
