Abstract
When a master hologram is to be formed in this method, a diffusing screen image is output as object light onto a first recording surface 12 via a lens 8'. When a slave hologram is to be formed, a second recording surface 12' is placed in a position where an image of the object light is formed by the lens 8'. In this method, the distance between a diffusing screen 7' and the first recording surface 12 when a master hologram 12' is recorded can be made different from the distance between the master hologram 12' and the second recording surface 12' when a slave hologram 12' is recorded. By varying these distances as needed, a hologram can be formed using a small optical system.
