Hologram preparing method
First Claim
1. A method for producing holograms wherein a plurality of images displayed on a spatial optical modulating element or diffusion screen are used as object light, through a lens array composed of a plurality of lenses disposed corresponding to the respective images included in the object light and a reducing optical system for reducing the object light emitted from said lens array, said object light is made to irradiate the recording surface along with a reference light;
- thereby interference light between said object light and said reference light is recorded on the recording surface, characterized in thatpartitions for separating said respective images are provided at least between said spatial optical modulating element and said lens array.

Abstract
In the method for producing holograms, a plurality of images displayed on a spatial optical modulating element 6 is used as the object light. Through a lens array 7 composed of a plurality of lenses disposed corresponding to each of the images, which are included in the object light, and a reducing optical system 9 and 10 for reducing the object light emitted from the lens array 7, the object light is made to irradiate a recording surface 11 along with a reference light; thereby interference light between the object light and the reference light is recorded on the recording surface 11. Between the spatial optical modulating element 6 and the lens array 7, partitions 15 for separating the respective images are provided; thereby noise is reduced.
