Abstract

In this article we have explored the use of Mueller polarimetry for the simultaneous and non-destructive latent fingerprint development and background elimination. This proposal not only expands previously reported uses of the polarization state of light for fingerprint development, but offers some advantages. Samples of a few donors, taken on different heavily back grounded substrates, were measured and processed. Several strategies for background removal were applied. The results are very promising, since the background was successfully erased in all cases and the quality of the developed fingerprints was excellent for most substrates and donors. Considering that the method is non-destructive and that the proposed measurement instrument is inexpensive and portable the method could be tried in real cases with no risk for the evidence. In addition, the success of the procedure for background removal raises the possibility of exploring if it would work for the enhancement of fingerprints developed with other methods.

穆勒偏振法无损潜指纹显影及背景消除

在这篇文章中，我们探讨了使用穆勒偏振法的同时和无损的潜在指纹显影和背景消除。这一提议不仅扩展了之前报道的偏振态光用于指纹显影的用途，而且提供了一些优势。在不同的重度背接地基质上采集的一些供体样本进行了测量和处理。应用了几种消除背景的策略。结果非常有希望，因为在所有情况下背景都被成功擦除，并且对大多数基材和供体的指纹质量都很好。考虑到该方法是非破坏性的，并且所提出的测量仪器价格便宜且便携，该方法可以在实际情况下进行试验，而不会对证据造成风险。此外，背景去除程序的成功增加了探索它是否适用于用其他方法开发的指纹增强的可能性。

期刊介绍： Science & Justice provides a forum to promote communication and publication of original articles, reviews and correspondence on subjects that spark debates within the Forensic Science Community and the criminal justice sector. The journal provides a medium whereby all aspects of applying science to legal proceedings can be debated and progressed. Science & Justice is published six times a year, and will be of interest primarily to practising forensic scientists and their colleagues in related fields. It is chiefly concerned with the publication of formal scientific papers, in keeping with its international learned status, but will not accept any article describing experimentation on animals which does not meet strict ethical standards. Promote communication and informed debate within the Forensic Science Community and the criminal justice sector. To promote the publication of learned and original research findings from all areas of the forensic sciences and by so doing to advance the profession. To promote the publication of case based material by way of case reviews. To promote the publication of conference proceedings which are of interest to the forensic science community. To provide a medium whereby all aspects of applying science to legal proceedings can be debated and progressed. To appeal to all those with an interest in the forensic sciences.
