OPTICAL CHARACTERISTICS OF THE BODY IMAGE

//The body image does not fluoresce in the visible light under ultraviolet illumination (A24) and emits radiations in the 8-14 micrometers infrared range (A29); the non-image area fluoresces with a maximum at about 435 nanometers (A25). The Shroud does not show any phosphorescence (A27) and redder fluorescence can be observed around the burn holes from the AD 1532 fire (A26). IR photograph of the face, if compared with visible ones indicates the low absorption near the IR (B20). All the chemical and microscopic properties of dorsal and ventral image fibers are identical (A28). The image of the dorsal side of the body shows fairly the same color density and distribution as the ventral (B19). The fibers in non-image (background) areas show the same type of superficial color as body image fibers, their spectra are the same(A23) If a fiber is colored, it is uniformly colored around its cylindrical surface; relatively long fibers show variation in color from non-image to image area (B15). Where one of the image-yarn crosses over another, there is often no color on the lower one (B18).
