HolAster : holography and astronomy

February 2018

Back to my Lorraine’s roots after the opal adventure, in Kleindal, a small village near Metz, I launch a new lab for art holography and holograms of astronomical objects. On this website I provide historical documents on the production of Ap-holographie, IDHOL and other labs, starting with Sérimage-holographie in 1977. My Veneto’s origin and relationship lead me to the purchase a nice telescope near Venezia, it is now grounded in a new astronomical observatory close to the holographic table. Moreover, I’ll keep busy the links with my holo-friends and the holography world.

A three lasers hello !

Image of the Sun diffracted by a Mezezo opal. The real image is floating 20 mm above the stone.

An now the sunset !

a : The light of the Sun diffracted by the opal.

b : The sunset diffracted by the same opal.

c : The same sunset diffracted by a reflection hologram*.
