posted on 2018-07-05, 09:16 authored by Elizabeth A. RaymondEmbossed holographic elements, such as diffraction gratings, display holograms and optical discs
are now firmly established as mass-replicated items. The embossed hologram has evolved from its original
form recorded in emulsion on glass plate to present-day images stamped
into plastic. The process of obtaining a holographic image in plastic
requires several stages of information transfer: first a surface relief
image must be recorded into emulsion; next a metal replica must be
made; finally the embossed plastic image is produced. A detailed
analysis of the information transfer process has been undertaken and is
described. [Continues.]
