Shroud of Turin

The work of Miklavcic and his colleague Li Yang (of China Medical University) on the theory of light scattering in absorbing media [1,2] has been used to analyze the seventeenth century Shroud of Arquata, a copy of the Shroud of Turin[3]. The theoretical model is used to assess the nature of the low-contrast, body impressions in the cloth simulating those in the Turin shroud. The Yang-Miklavcic theory has also been employed to analyze the reason for the degradation of a Leonardo da Vinci self-portrait [4] and assist in identifying physical-chemical conservation methods to prevent further degradation.
