Corona discharge to explain the image of the Turin Shroud: Experimental results

摘要

Corona Discharge (CD) has been considered as a way to produce marks on a linen tissue and then as one possible explanation of the image observed in the Turin Shroud (TS). We used CD to produce images on linen from two silver figures. Their photograph negatives resemble that of the TS. Discussion of the CD produced images is presented. Also, breaking resistance of the linen threads was measured as function of the bleaching time. Infrared spectra from the linen and from the image produced by CD are also included.
