In the website of our laboratory is the web page where you can find all the results,
works, publications, interviews and films related to the Shroud studies conducted at ENEA.

From a Google translation of an interview conducted by Maria Margherita Peracchino in L’Indro, Shroud: the image impossible according to the ENEA: Interview with Paolo Di Lazzaro, head of the Laboratory of the Center Excimer ENEA Frascati:

Among the most recent studies, there is one made by the Laboratory of the Center Excimer ENEA Frascati. "Our laboratory has tried a new approach," says Paolo Di Lazzaro, head of the Laboratory of ENEA Frascati, "trying to play a Shroud-like coloration of linen fabrics through photochemical effects induced by ultraviolet light, which in principle has the characteristics needed to get at least two of the characteristics of the Shroud image, which is the low temperature of formation and coloring extremely superficial, limited to a thin film sub micrometer. "

Lazarus, we explain the work you have carried out on the Shroud and the fundamental results to which you have come?

Since 2005 the Laboratory of Excimer ENEA Frascati Centre carried out a large number of irradiation of ultraviolet laser light on linen fabrics woven in the years between 1930 and 1950 never used and never washed with detergent, in order to avoid the presence of bleaching chemicals that can alter the optical properties of the tissue. By radiation means sending laser pulses on the fabric, which alter the chemical bonds of the same tissue, which in turn changes its surface properties and appearance. The main purpose of irradiations was to verify whether an intense ultraviolet radiation was able to create a linen coloration with characteristics similar to those of the body image on the Shroud of Turin. After numerous irradiation and with great difficulty we managed to find the right combination of laser parameters (pulse duration, intensity, energy density and number of shots) that allows a color-like shroud. We got a shade of color, a superficial staining, an effect of alternating colored fibers and not colored, the negativity of the image that are similar to those measured on the Shroud of Turin by STURP. Based on our thirty years of experience of irradiation and interaction of light with many materials, was the first time that we have found a range of values ​​so critical to get the desired effect: during the irradiation of the fabric is in fact sufficient to vary by a few percentage points one only the laser parameters mentioned above to stop getting any coloration of linen. Really amazing.

In addition to the experiments of laser irradiation and coloration of linen, more recently you have faced the problem of different written and invisible images that some scholars fail to highlight after a digital processing of the contrast and brightness of the photographs of the Shroud.

Yes. And our results suggest that in some cases (the alleged written, the alleged face on the back) is probably illusory perceptual effects related to the phenomena of psychological Gestalt and pareidolia well known to scholars of human perception and optical illusions. Our results have been presented in detail in several articles published in international scientific journals of great prestige and impact, and therefore are available to all interested scientists to reproduce our results and maybe get better. In the website of our laboratory is the web page where you can find all the results , works, publications, interviews and films related to the Shroud studies conducted at ENEA.

“There’s only one answer: This cloth wrapped the body of Jesus.”  — Barrie Schwortz

imageIn Denver’s Westward, Patricia Calhoun writes: Jesus! Was the Shroud of Turin Created by a Supernatural “Flash of Light”?:

According to Vatican Insider, experts at Italy’s National Agency for New Technologies, Energy and Sustainable Development have concluded that what’s been billed as the burial cloth of Jesus Christ could not have been faked:

“The double image (front and back) of a scourged and crucified man, barely visible on the linen cloth of the Shroud of Turin has many physical and chemical characteristics that are so particular that the staining which is identical in all its facets, would be impossible to obtain today in a laboratory … This inability to repeat (and therefore falsify) the image on the Shroud makes it impossible to formulate a reliable hypothesis on how the impression was made.”

Their study involved a lot of technical use of laser lights — pulses in short-term duration — and also name-checks some of the research done by the Shroud of Turin Research Project headed by John Jackson, who led a STRP team of researchers to Italy back in 1978, and still runs the Turin Shroud Center in Colorado Springs. “It seems as though they’re cueing off a paper that I did about twenty years ago on image-formation mechanism,” Jackson says. “There’s some essential physics here. I’ve thought for twenty years that ultra-violet could create a vision.”


Jackson has been trying to solve that puzzle for decades….

“Coloradans have played an important role in Shroud research,” notes Barry Schwartz, publisher of the Colorado-based He was part of the team that went to Italy in the ’70s (he only moved to this state five years ago) and has done much of the photographic documentation.

The Italian research, he says, “further supports the scientific data that the image on the Shroud is neither a painting or art or a hoax from the medieval times to fool us.”

Jackson will continue to push for more proof of what, exactly, the Image is. “We keep pressing forward as best we can,” he says. “I would commend the Italian researchers. They’re trying to understand the shroud using a radiation model…I’m pleased that they’re using capabilities that they have to try to explore that type of a hypothesis.”

But Schwartz, who is Jewish and says he was “the biggest skeptic on the team,” is ready to make a more definitive pronouncement: “There’s only one answer: This cloth wrapped the body of Jesus.”
