Holograms rediscovered: a case study on the preservation of a hologram collection

There is growing global interest in using holography to preserve cultural and historical artifacts. A recent study on our university’s history, in collaboration with PATSTEC and the Musée des Arts et Métiers, led to the rediscovery of extensive holography work from 1965–1980. During this period, our laboratory used laser-based holography to record significant cultural pieces, in collaboration with fashion houses, artists, and museums. Over 200 holograms have survived in excellent condition, showcasing pioneering techniques such as real and virtual image combinations, white light animation, and deep-field volume holograms. The collection includes early methods like Leith, Denisyuk, and Benton (Rainbow) holography. A standout is a life-size hologram of the Venus de Milo, made with the Louvre. Internationally recognized, this work helped link science and society. Rediscovered photographs and interviews further enrich the archive. This paper explores lessons for modern holography in heritage preservation and how to display these holograms using simple, modern equipment.
