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 laser communications superhighway. You will need the Adobe Acrobat PDF reader for this file.


Christian Holography Research
Objectives: (1) to help place the Holy Bible in areas of the world where more traditional evangelistic methods are dangerous, even life threatening (stealth technology); (2) to research archival recording methods for Scripture and historical artifacts (3D laser holograms); (3) to one day communicate the Gospel to other worlds beyond our own: from upcoming human colonies on the Moon and Mars, to the deepest regions of outer space (space based laser communication); (4) to prepare youth for the evangelism of the future, utilizing (and further developing) these new technologies.

3D Holograms from Outer Space!
NEW FOR FALL 2014: After 32 years of providing traveling presentations, this is the final show of my lifetime in holography. "3D Holograms from Outer Space!" is a fun, educational, 'far-out' presentation for students to learn about the future of laser communication technologies. As a table top presentation, it is geared for the smaller, single classroom and home school groups: late elementary to middle school. I hope to continue with this theme until my official retirement at the end of 2017. MORE INFO...

Located in the historic district of Allentown, Pennsylvania. A short drive from both Philadelphia and New York City.

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 plus years of award-winning service to the laser and holography fields of art, science and technology.

Holography Workshops
My holography workshop program has been running since 1983: gas & diode lasers, gelatin silver glass plates, wet processing in darkroom, 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 presented by someone with 30+ years of real-world experience. Be safe and be sure right here.

What Is A Hologram?
What makes a hologram work? A primer about the making and usage of holograms in today's (and tomorrow's) world. Gives examples in art, science and technology applications. If you're wondering what holography is all about, don't pass this page without first taking a look.

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.

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.

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.
