The unique reddish blood stains on the archaeological cloth known as the Shroud of Turin caught the attention of several scholars, who proposed different hypotheses to explain the unusual blood color. To date, just a few hypotheses have been tested experimentally, and the results are debatable. In this paper, we test the strength of two hypotheses (namely, the presence of carboxyhemoglobin and the long-term influence of ultraviolet light on high-bilirubin blood) by the spectral reflectance of the blood stained regions on the Shroud and by color analyses of ultraviolet irradiated high-bilirubin blood stains on linen. The relevance of these simple methods to the study of stained textiles is discussed.
在被称为都灵裹尸布的考古布料上独特的微红血迹引起了几位学者的注意，他们提出了不同的假设来解释这种不寻常的血迹颜色。到目前为止，只有少数假设经过了实验验证，而结果仍有争议。在本文中，我们通过对裹尸布上血迹区域的光谱反射率以及对亚麻布上紫外线照射的高胆红素血迹进行颜色分析，来检验两个假设（即羧基血红蛋白的存在以及紫外线对高胆红素血液的长期影响）的可信度。本文还讨论了这些简单方法在研究染色纺织品方面的相关性。
