HOLOGRAM PREPARING METHOD

摘要

A hologram preparing method,wherein an object light including a plurality of images displayed on a spatial light modulation element(6)is beamed together with a reference light onto a recording surface(11)via a lens array(7)consisting of a plurality of lenses disposed in conjunction with individual images(s)included in the object light and reduction optical systems(9,10)for reducing the object light emitted from the lens array(7),and interference light between the object light and the reference light is recorded on the recording surface(11).Partitions(15)provided between the spatial light modulation element(6)and the lens array(7)to isolate individual images from each other reduces noise.
