Paper Abstract

Display holography in Latvia goes back to two different sources. First, amorphous films of chalcogenide semiconductors yielding a surface microrelief after exposure and development have been investigated at the Institute of Physics at the Latvian Academy of Sciences in the late 1970's up to now. Second, techniques for making laser- and white-light holograms of various types have been developed at the holographic training laboratory of the University of Latvia in the 1980's. After development the technology for a complete process of mass-production of rainbow holograms in the mid 1990's the two holographer groups combined their efforts in the field of commercial holography. To this purpose the firm `Dardedze holography' Ltd. has been established. There are also `Hologramma' Ltd. in Riga and `Difraks' Ltd. in Daugavpils active in commercial holography.
