A new, to our knowledge, method for recording rainbow holograms of three-dimensional diffused objects in one step without the use of slits is proposed. No lens is needed for recording in this kind of holography; instead, multiple synthetic slits are created by displacement and multiple exposure of an object to expand the horizontal and the vertical viewing angles of the hologram.
