Paper Abstract

A ultra-high sensitivity holographic Ultimate emulsion (10nm grains) has been produced, which allows the realization with short exposure times of bright, large sized, with wide view angle and full color holograms of fragile still subjects of monochromatic pulsed reflection holograms of alived subjects. The high transparency of Ultimate emulsions as color transmission holograms makes them highly suitable for mastering, the copies keeping the same performances as the master. Copies on other materials, especially polymer emulsions are possible. Coating machines have been performed for the production of 36 x 44 cm triacetate films and 60 x 84 cm glass plates under controlled conditions of temperature and humidity. Also, a homemade portable camera with pulsed YLF or ruby lasers allows to realize holograms in situ of alive subjects on H1 transmission holograms up to 60 x80 cm and instant H2 reflection copies up to 30 x 40 cm. Some examples of holograms are displayed.
