红外线反射照相显现深色纺织品上的字迹

Infrared Reflection Photographic Technique for the Development of Handwriting on Dark Textiles

目的研究红外线反射照相对深色纺织品上模糊字迹和消褪字迹的显现效果。方法运用红外线反射照相对三种纺织品上的四种模糊字迹和消褪字迹进行显现。结果红外线反射照相能够显现部分纺织品上的部分字迹,且显现效果与滤光镜的波段有关。结论深色纺织品上模糊字迹和消褪字迹的显现与书写色料、纺织品的种类和拍照时使用红外滤光镜的波段有关。

Objective To study the effect of infrared reflection photographic technology for the development of fuzzy handwriting and faded handwriting on the dark textiles. Methods Reveal the four kinds of fuzzy handwriting and faded handwriting on three kinds of fabrics through the infrared reflection technique. Results The infrared reflection photographic technique can display the part of handwriting on part of the textile, and the effect is related to the band of the filter. Conclusion Whether the handwriting can be exposed concerns the writing pigment, the textile and the infrared filter.
