ABSTRACT:
In the method for producing holograms, a plurality of images displayed on a spatial optical modulating element6is used as the object light. Through a lens array7composed of a plurality of lenses disposed corresponding to each of the images, which are included in the object light, and a reducing optical system9and10for reducing the object light emitted from the lens array7, the object light is made to irradiate a recording surface11along with a reference light; thereby interference light between the object light and the reference light is recorded on the recording surface11. Between the spatial optical modulating element6and the lens array7, partitions15for separating the respective images are provided; thereby noise is reduced.
