Reigate Hill Rotary Holography

I was invited to give a holography demonstration -along with a talk on Photonics- to members of the Rotary Club of Reigate Hill on October 10, 2007. Approximately 20 members of the club listened politely to my talk and watched a hologram being made in the Restaurant at the Reigate Manor Hotel.
I'm pictured here explaining how laser light hits the holographic plate - from above and below - in order to produce the holographic image on the plate (at least that's what I think I was saying!).
It's amazing that you can now make a hologram on a restaurant table infront of a room full of people - thanks to some cutting-edge technology. My holography rig was supplied by Mike Anderson [contact me if you'd like his address] with holography plates and chemistry purchased from Integraf. The equipment and holography materials allow a 12 second exposure of an object with a laser safe to use in public and a 10 second developing time.
The President of the Club Maggie Jackson made the hologram infront of the hushed audience, and my Father Michael John, (member of Reigate Rotary Club) is shown here drying the hologram with a hair-drier.
Pip Ward - a member of the Rotary Club - views a display hologram after the demonstration.
I was very grateful to learn that the members distributed schools' information packs to their local schools as a result of attending the talk which encouraged everyone to support their children and grandchildren (particularly girls) to take part in science at school and at home.
Thanks to Maggie Jackson for the invite - and to Michael Jones for the photographs.
