A technique for recording two-dimensional rainbow holograms by use of
a nonlaser light source is described. Multicolor holograms are recorde
d in one step. The optical setup is lensless. The recording light sour
ce is an InGa lamp that provides a spectrum from UV to blue. The slit
effect is generated by replication from the slit master plates. (C) 19
