摘　　要：探究有色布料上的签字笔墨迹光学显现的可行性及其影响因素。收集不同颜色、类型的签字笔和布料,共制作有色布料上签字笔墨迹样本64个。基于光致发光原理,利用视频光谱仪,选择不同激发光源波段和摄像机滤色片进行组合,对样本进行检验。实验结果表明,光致发光原理可以有效显现有色布料上的墨迹,显现效果受激发光波长、滤色片类型、布料种类、油墨浓度、遗留时间的影响。Explore the feasibility and influencing factors of signature ink on colored cloth.Collect pens and fabrics of different colors and types,and make a total of 64 samples of pen ink on colored fabrics.Based on the principle of photoluminescence,the video spectrometer selects different excitation source bands and camera filter to test the samples.The experimental results show that the principle of photoluminescence can effectively show the ink marks on the colored cloth,and the effect is affected by the excitation light wavelength,type of color filter,type of cloth,ink concentration and legacy time.
