The Spectroscopy of Various Candidate Processes Associated with Image Formation and Features of the Shroud of Turin Redux (What We Might Have Seen If We Did It Right) by Joseph S. Accetta (email@example.com). Friday, August 15, 11:00 a.m.–11:30 a.m.
This paper begins with a brief review of the spectroscopy of materials and the potential information available from various spectral techniques. The 1978 infrared spectroscopic investigation is briefly discussed and lessons learned followed by a presentation and discussion of the spectroscopic data associated with various theories of image formation including several manifestations of degraded cellulose, blood, pigments and other substances that may be present. The paper concludes with commentary on future investigations including both destructive and non-destructive spectroscopic techniques that may be brought to bear on the chemistry of the cloth.
