ABSTRACT:
A method of producing a hologram with an orthoscopic, at least partially real image of an object is disclosed. According to the method, the object is recorded on a first hologram and is then reconstructed from this hologram and recorded on a second hologram. In taking the second hologram, solid objects are situated laterally with respect to the light-wave field reconstructing the object from the first hologram, and the solid objects are included in the second hologram. This technique permits reproduction of an image of the object which is viewable over a greater spatial region than would be the case if the laterally situated solid objects were omitted.
