Shroud Of Turin

The Raman spectrum of a microsubstance, smeared on a fiber coming from the Shroud of Turin, was compared with numerous spectra published for old or modern pigment dyes, whole bloods, dried bloods, red blood cells, albumin, very ancient blood stains, and various “degradation” products of heme. Within the wavenumber measure accuracy, it is shown that all Raman lines detected above background could correspond to vibration frequencies found in biliverdin-derived compounds except a weak line that we tentatively attributed to amide I. Biliverdin is known as an oxidative ring cleavage product of the heme of blood. Energy dispersive spectroscopy (EDS) analysis of the sample confirms an elemental composition fully compatible with this hypothesis. Therefore, it is very likely that this microsubstance contains products of heme including heme/biliverdin-derived compounds and protein traces (amide I). Nevertheless, other measures will be necessary to confirm it. This method of identification, adding EDS to Raman spectrometry can be applied to nondestructive testing (NDT) of many other microsamples.

Fluorescent Screen

In this form of electron microscopy, photoelectrons emitted from a metal by ultraviolet radiation are accelerated and imaged onto a fluorescent screen by conventional electron optics. image contrast is determined by spatial variations in the intensity of the photoemission. The dominant source of contrast is due to changes in the photoelectric work function, between surfaces of different crystalline orientation, or different chemical composition. Topographical variations produce a relatively weak contrast due to shadowing and edge effects.Since the photoelectrons originate from the surface layers (e.g. ∼5-10 nm for metals), photoelectron microscopy is surface sensitive. Thus to see the microstructure of a metal the thin layer (∼3 nm) of surface oxide must be removed, either by ion bombardment or by thermal decomposition in the vacuum of the microscope.
