Shroud of Turin Laser Research

Utilizing 3D laser holograms, combined with 3D stereo microscopes, the Shroud of Turin can be visually examined by anyone, anywhere in the world.

Archive of Holoworld:

HoloWorld went online on Tue, 04 Dec 1993 21:29:02 GMT (as the Internet Webseum of Holography) during the era of dial-up 14.4 modems and NCSA Mosaic browsers. Chronologically archived copies of the entire HoloWorld web site can be found at the Internet Archive Project. It had been archived 601 times between 5 Nov, 1996 and 7 Dec, 2016. As such, it preceded the Internet Archive itself by nearly three years: | 1996 | 1997 | 1998 | 1999 | 2000 | 2001 | 2002 | 2003 | 2004 | 2005 | 2006 | 2007 | 2008 | 2009 | 2010 | 2011 | 2012 | 2013 | 2014 | 2015 | 2016 |

Holograms, Light and the Word of God: Energy and power are contained in the light spoken into existence by Jesus Christ on Day One of Creation. He is the awesome and powerful Creator of the universe. This paper / lesson shows the connection between holograms, light, and the Word of God.


The Shroud of Turin is the most scientifically examined artifact in world history. Currently, it is a limited resource for scientists in that access for physical examination is restricted, while strictly visual examination relies on traditional photographic methods.

Holography is currently the highest resolution imaging technology in the world today. Holographic emulsions, whether silver-halide or photopolymer, support up to 10,000 lines/mm of resolving power.

Since the recording is holographic, the image of the fibers would remain three dimensional. The holographic recordings can then be duplicated, and sent to researchers around the world -- without the Shroud ever leaving its protective storage. I did not have access to the Shroud of Turin (nor does anyone else in 2017), so I will utilize a similar piece of herringbone linen for my holograms.

For my microscope holograms, I will utilize a similar piece of herringbone linen to that of the Shroud of Turin.

I have demonstrated in the past that it is possible to record 3D laser holograms on thin-film photopolymer emulsion, then reconstruct the holograms for viewing under high-power 3D stereoscopic microscopes. This gives the same result to the observer as the object physically being there: it can be examined with just as much authority as the "real thing".

This is not the first time that holography / holograms have been applied to Shroud research. Within the past decade, there have been other holograms made, most notably the famous "Face in the Shroud". However, these are display holograms: projects primarily for the dimensional properties of the *image* in the shroud. They did not provide the ability to examine the fibers of the cloth itself under high powered microscopes in three dimensions. My enquiry is for scientific and technical purposes, not for display, and should not be compared in any way to previous work by others (as fascinating and important as that work has been, of course). I would just like to distinguish the difference between the two efforts.

My work began in September 2017. Although recently retired and no longer having access to my 35-year holography laboratory, I managed to set up a small holographic recording area in my current retirement residence. Since I wrote the book on creating small scale holograms easily and affordably, I had better be able to pull this off. It was a success. I displayed and demonstrated this work at the 2017 World Maker Faire, New York Hall of Science, September 22 and 23, 2017, and will be including it in my other traveling presentations for the Fall season of 2017 and beyond into 2018.

As was predicted, the 3D laser holographic (hologram) image of the linen sample appeared just as the actual physical linen would when placed under any 3D stereo microscope. Each individual fiber was clearly discernible. If this hologram were made of the actual Shroud threads, any scientific laboratory anywhere in the world would be able to visually examine it. Being easily duplicated once created, many laboratories would have "access" to 3D stereoscopic visual examination of the Shroud of Turin.
