Coloring linens with excimer lasers to simulate the body image of the Turin Shroud.
نویسندگان
چکیده
The body image of the Turin Shroud has not yet been explained by traditional science; so a great interest in a possible mechanism of image formation still exists. We present preliminary results of excimer laser irradiation (wavelength of 308 nm) of a raw linen fabric and of a linen cloth. The permanent coloration of both linens is a threshold effect of the laser beam intensity, and it can be achieved only in a narrow range of irradiation parameters, which are strongly dependent on the pulse width and time sequence of laser shots. We also obtained the first direct evidence of latent images impressed on linen that appear in a relatively long period (one year) after laser irradiation that at first did not generate a clear image. The results are compared with the characteristics of the Turin Shroud, reflecting the possibility that a burst of directional ultraviolet radiation may have played a role in the formation of the Shroud image.

The faint body image embedded into the Turin Shroud has not yet explained by science. We present experimental results of excimer laser irradiation (wavelengths 308 nm and 193 nm) of a raw linen fabric and of a linen cloth, seeking for a possible mechanism of image formation. We achieved a permanent coloration of both linens as a threshold effect of the laser beam intensity. The coloration is ob...

We present a survey on five years of experiments of excimer laser irradiation of linen fabrics, seeking a coloration mechanism able to reproduce the microscopic complexity of the body image embedded onto the Shroud of Turin. We achieved a superficial, Shroud-like coloration in a narrow range of irradiation parameters. We also obtained latent coloration that appears after artificial or natural a...
متن کاملThe double superficiality of the frontal image of the Turin Shroud
Photographs of the back surface of the Turin Shroud were analysed to verify the existence of a double body image of a man. The body image is very faint and the background not uniform; i.e., the signal-to-noise ratio is lower than one. Therefore, image processing, developed ad hoc, was necessary to highlight body features. This was based on convolution with Gaussian filters, summation of images,...

The unique results produced by simple studies of the Shroud of Turin sets this particular artifact apart from all other known artifacts. When photographed, the Shroud image appears more clearly to the human eye in the photographic negative than in the photopositive. When image-processed by a VP-8 Image Analyzer, the Shroud image produces a three-dimensional response unlike any other image so pr...

The Shroud of Turin is a large piece of linen that shows the faint image of a man on its surface: it has been claimed to be the shroud of Jesus. Here we report evidences that colour can be produced by reactions between reducing sugars, left on the cloth by the manufacturing procedure, and amines deriving from the decomposition of a corpse. Treatment of a cloth prepared according to the ancient ...
