Australian Holographics

Australian Holographics was started with the specific objective to produce high quality large format holograms. After two years of research and development the company began commercial operations in 1991.

Situated on 80 acres (320,000 m2) of rural farm land 25 miles (40 km) from Adelaide, the lab's facilities included a 5 x 6 metre vibration isolation table in a studio with air-lock loading doors, large enough to drive a car onto the main table. The main laser was CW (continuous wave), 6W argon laser built by Coherent Scientific. The company also used a 3 joule ruby pulse laser, built in collaboration with Professor Jesper Munch of the School of Chemistry and Physics at Adelaide University.

The company mainly specialized in the production of the large format white-light-viewable Rainbow hologram, a type of holography originally invented in 1968 by Dr. Stephen Benton of MIT. IN fact, while all Rainbow Holograms are 'white-light-viewable' the most commonly known application of the technique has been applied to reflectve substrates like PVC (Polyvinyl Chloride) and PET (Poly Ethylene Terephthalate) and used widely on credit cards and as anti-counterfeiting applications on labeling of products. Australian Holographics applied the principle for transmission rather than reflective viewing conditions. In 1992, Australian Holographics produced a 2 x 1 metre rainbow transmission hologram of a Mitsubishi Station Wagon car, which was shown at Holographics International '92 conference in London.
