| 中文摘要:目的 研究涉案ATM机打印凭条上潜在字迹的显现方法,为查明案情提供技术支撑。 方法 在365-620nm的范围内选取7个波段的光线作为入射光照射检材,在可见至近红外区选取14个波段分别成像记录检材的发光亮度分布。结果 用580nm的黄橙色入射光照射检材,在垂直方向上透过780nm的近红外长波通滤光镜接收记录检材的发光亮度分布,可以较清晰地显现出亮字暗背景的潜在字迹。结论 利用红外发光成像技术可以显现ATM机打印凭条上的潜在字迹。 |

| Abstract:Objective Study on the technical approach of detection of latent numbers on the receipt of ATM, To identify the facts of the case to provide technical support. Methods Selected seven bands of light In the range of 365-620nm,then radiation the samples one by one, recorded the fluorescent luminance of samples at 14 bands in range of 400-950nm. Result Radiation the samples with the light at 590nm,and recorded the fluorescent luminance at 780nm,can be show the latent numbers clearly on the receipt of ATM. Conclusion The IR fluorescent photography technology can be used in detection of latent numbers on the receipt of ATM. |
