Lasers, Holograms & Photonics (download)
Here is an 18-page study guide (PDF format) and homework helper that will give students a good foundation with lasers, holograms and the field of optics / photonics. It provides definitions, a timeline of events, biographies of inventors, along with current and future applications. The future is made of LIGHT, and those who are able to understand and work with light will pave the way for the photonics-based, free space laser communication technologies superhighway.

VISIT MY HOLO-ROOM IN ALLENTOWN, PA
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
Who Is 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.

My Christian Based Work
w/ Cutting-Edge Holographic
Holograms are not just about 3D images. When holography was invented, the 3D aspect was a "side-effect" not a main objective. Holography was invented as an improvement to electron microscopy. The REAL future of holography will be its many technical applications. Here are a few of my recent projects utilizing laser holograms in a slightly different than usual way: making sure that the Holy Gospel is taken far into the future and beyond earth.
Introduction to Micro Holography (download)
Here is an introductory 12-page PDF file with photos that gives a bit of history behind holograpic microscopy (going back to the 1960s). I wrote this for the British online magazine Micscape for September 2013. You will need the Adobe PDF reader in order to read this document.
The Hologram Bible (web page)
The Hologram Bible contains all 1,245 individual pages, and 773,746 words of the King James Bible. It is the size of an average snowflake. Its mission is to safely bring Scripture to areas of the world where the Christian Holy Bible is banned. Its size is just the beginning of what makes it different from every other Bible in the world today. Seen by thousands.
World's Smallest Lord's Prayer (web page)
Is this laser hologram the 'Greatest Hologram on Earth'? The width of a single human hair, I propose that this is the world's smallest rendition of the Lord's Prayer in the world today. It contains its own magnification optics encoded into the hologram itself. Reported in many top newspapers across the USA and NBC 10 (Philadelphia) in Sept. 2013, and shown in many science museums and expositions including the Smithsonian and the New York Hall of Science. Seen by tens of thousands.
3D Life of Jesus (@ Flickr)
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.
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.
My trinity of light-based
interests and experimentation:
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.
Holography at Planet Saturn
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.
