HoloWorld went online on Tue, 04 Dec 1993 21:29:02 GMT. My name is Frank DeFreitas and I am an elected member of Sigma-Pi-Sigma; National Physics Honor Society; American Institute of Physics for my work in laser and holography educational programs. My work includes the Smithsonian Institution, Washington D.C. (Hirshhorn & Ripley Education Center, ongoing), The Franklin Institute, Phila; Liberty Science Center, NJ; The Discovery Center of Science and Technology, PA; Lehigh University Physics Dept.; Lehigh-Carbon Community College; Georgian Court University Physics Dept.; the Urban Systemic Initiative (NSF); and many elementary, middle and high schools / home school programs throughout the northeast region -- along with several National Science Foundation-funded programs in other regions of the U.S.A. and the first-ever online class for holography, through America On Line, in 1995. If you like what you see, please share HoloWorld with others.
I have over 20,000+ items in my history of holography collection. After collecting for over 35 years, I began putting them on display. Lo and behold, people started visiting from around the world! My exhibit for 2014 is: 150 Years of Christian 3D: from Stereo Photography to Laser Holography. This is an exhibit that documents the relationship between Christianity and nearly two centuries of cutting-edge 3D imaging science and technology. Everything in this current exhibit is centered around the life of Jesus Christ. "There is nothing else like it in the world today". -- Frank DeFreitas
You wouldn't go into a strangers house, would you? I didn't think so! Web sites are no different! Before you begin your visit here at HoloWorld, take a few minutes to learn about your host (me), and my 30 years of award-winning service to the laser and holography fields of art, science and technology.
Holograms may be the best 3D today, but they weren't the first! Taking over a full year to complete, this gallery shows the earthly life of Jesus in 3D. Viewable on any computer screen, these anaglyph pictures were hand-created from vintage stereographs. Some go back to the 19th century! To view them, they require the standard red (left) / cyan (right) 3D glasses. If you do not have a pair of glasses: I will be happy to send a pair to you (USA only) without charge. Just call, write or email with your postal mailing address HERE.
Holography Workshops & Outreach
My RETRO / VINTAGE HOLOGRAPHY workshop program focuses on the way holograms were made in the very early days: gas lasers, gelatin silver glass plates, wet processing, hand-made optical components and vibration-isolation tables. This is laser holography at its DIY best.
Holography for Kids
This is the original online laser and hologram science learning page for students. Today's youth are the future of this emerging technology. A great resource for home schoolers, too. One of the few laser and hologram resources online that is put together by someone with 30+ years of real-world holography 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.
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.
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.
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.
How To Make A Hologram
Want to know how to make a hologram? Step into my laser lab and see how it is done, with step-by-step DIY photos. All of it possible in your own home or school. You can print out this page for reports and homework.
My Holographic Light Art
Abstract art created by passing light through holographic optics and quartz crystals known as Cape May Diamonds. Shapes, colors and patterns never before seen are revealed, after being encoded in the crystals since their creation. Includes my holographic light art gallery.
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 basement labs -- 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 holography history.
Memories of Edmund Scientific Co.
Share my memories of the once-great Edmund Scientific factory store in Barrington, New Jersey. In 2012, I will be adding photos of all of my Edmund memorabilia, going back to the 1960's. Includes info. on their famous Light Show Theater. Enjoy!
The ultimate (and original) guide to laser and holography collectibles. Covers everything from holograms to advertising to posters and post cards (and more). For nearly twenty-five years, this guide continues to be an inspiration for people all over the world to begin their own collections.
The First Twenty Years
This section shows twenty holograms from the first twenty years of my studio / lab in Allentown, Pa. Each piece is accompanied by an audio file describing the work. Years covered are 1983 through 2003.
My published article on holographic principles and coherent thought. 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
"HoloTalk" began broadcasting online in 1997 (!) with its now-famous mix of interviews and topical discussions, the show features host Frank DeFreitas and guests from around the world. For nearly fifteen years, listeners made "HoloTalk" a part of their online routine. Over 100 shows are now available in the MP3 archive.
Download a back issue of HoloWorld: The E-Zine of Popular Holography. Each issue contained news & information, tips & tricks, history, reviews, net treks, and more.
The Civil War Holography Project
See this exciting Civil War holography project with students of Englewood High School in Jacksonville, Florida. Priceless treasures have been at the bottom of the St. Johns river since 1864. These historical artifacts are now recorded as holograms. Includes PBS video.
