A technique for recording two-dimensional rainbow holograms by use of a nonlaser light source is described. Multicolor holograms are recorded in one step. The optical setup is lensless. The recording light source is an InGa lamp that provides a spectrum from UV to blue. The slit effect is generated by replication from the slit master plates.
