One of the few laser and hologram resources online that is presented by someone with 30+ years of real-world experience. Be safe and be sure right here.
Hologram of the Moon
Blue Ribbon Winner, New York Hall of Science, 2011.
In 2011, I produced an award-winning 3D laser hologram of the moon. It was (and remains) one of my most ambitious holography projects. The two ground-based, telescopic photographs that make up this 2-channel holographic stereogram were taken 150 years apart.
3D MPO Voyage to the Moon
(Le Voyage dans la Lune)
Download these 3D MPO files and journey on your own Voyage to the Moon (3D Le Voyage dans la Lune). I've taken 16 of NASA's most famous Apollo program stereo photographs and made them into digital files for today's 3D hand-held devices (Nintendo 3DS, Fuji Real 3D and SONY PS3). You will think that you are standing right on the edge of craters on the surface of the moon. Featured as a Pick of the Month in 3D Focus magazine, December 2011.
Make Your Own Victorian Stereoscope
Holograms are the ultimate in 3D, but long before laser holograms arrived on the scene, people enjoyed 3D images through the Victorian stereoscope. On this page, I show how I assembled one of the DIY kits available today to hobbyists and makers. It is also relatively easy to make your own stereoview cards to view in the stereoscope.
My Name is on Saturn's moon Titan
Do you like astronomy? Do you like the great planet Saturn? Take a moment to read a fantastic story. It is the extraordinary (and true!) story about having my name on the surface of another heavenly body: Titan, the famous moon of the planet Saturn. It was the first landing ever accomplished in the outer solar system. If you love space, you'll love this story . . . and you'll never look at Saturn the same way again.
What Are Lasers Used For?
Perfect for reports and homework, this web page gives students of all ages a printable list of what lasers are used for today. Laser technology is all around us in our everyday living. Find out just how much this is true.
Making Holograms with Laser Pointers
Diode laser holography didn't begin in a professional laboratory, it began in three home basements -- and was documented every step of the way right here at HoloWorld. Here are the original project notes from start to finish. Includes the world's first hologram created using a solar powered laser. I am honored to have been part of this history. It changed the world of holography forever.
Memories of Edmund Scientific Co.
Share my 1960's memories of the great Edmund Scientific factory store in Barrington, New Jersey. Over time, I will be adding photos of all of my Edmund memorabilia and ephemera. Includes info. on their famous Light Show Theater. Enjoy!

Holographic Brain, Mind, Universe
My published article on holographic principles applied to everyday living. I keep it updated, current and revised online. From the Holo-Gram newsletter, and the Laser Arts Society journal (long before the Internet).
Holography Internet Radio Show
L-O-N-G before YouTube, iTunes, etc., "HoloTalk" began online broadcasting in 1997 (!). With its now-famous mix of interviews and topical discussions, I have been host to holography enthusiasts, collectors and practitioners ... even an Apollo astronaut that walked on the moon. With a run of over fifteen years, listeners made "HoloTalk" a part of their online routine. Over 100 shows are now available in the MP3 archive.
