Abstract

This paper describes hologram origination process combining rainbow and dot-matrix holograms. Rainbow and dotmatrix
holograms origination processes were combined to produce hologram showing different images. Both holograms
were recorded consequently in a photoresist layer on the same sample. Dot-matrix hologram origination process was
performed using laser diode PMMF 608-G at wavelength 405 nm. For rainbow hologram He-Ne laser (632.8 nm) and
He-Cd (441.6 nm) lasers were used. The combined holograms viewed at appropriate angle showed dot-matrix and
rainbow hologram images at the same time. Microanalysis of combined hologram surface demonstrated features, which
are typical for both dot-matrix and rainbow holograms processes.
