Paper Abstract

The old Lippmann color photography technique has been investigated. Today, high-resolution panchromatic recording materials are on the market suitable for Lippmann photography. The holographic panchromatic silver-halide materials from Slavich in Russia, as well as the panchromatic photopolymers from DuPont in the USA can be used for recording Lippmann photographs. In particular, the Slavich emulsion has been investigated for recoding Lippmann photographs. In order to understand the Lippmann technique better, computer simulations of the recording and reconstruction process have been undertaken. A Lippmann color photograph is unique and almost impossible to copy, which makes it suitable for the document security application. A new optical variable device (OVD) technique is under development. This type of photograph can be applied to personal documents as a new optical security device, e.g., passports, ID cards, etc., can carry a Lippmann OVD. The recording of a Lippmann photograph requires a special panchromatic recording material, e.g., silver halide materials or photopolymer materials.
