Patent attributes
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.
