摘要
本文提出一种基于相位敏感谱域光学相干层析术(spectral domain optical coherence tomography,SD-OCT)的遗留指纹获取方法,该方法具有非接触、无损、快速和高灵敏度优势.实验结果显示,即使在低对比度条件下,本方法也能较好地再现遗留指纹,证明相位敏感谱域光学相干层析术可以准确、可靠地识别潜指纹.
Despite the advances made in areas such as DNA profiling, fingerprints are stiU considered to be the best form of personal iden- tification for criminal investigation purposes. A variety of physical chemical and optical techniques are available for the enhancement and detection of latent fingerprints. However, existing frequently-used fingerprint detection methods show some disadvantages such as harm to fingerprints, slow extraction, potential side effects, leaving trails, high contrast demand and so on. A new method based on phase sensitive spectral domain optical coherence tomography （SD-OCT） for latent fingerprints detection is proposed. This method has advantages of non-contact non-destructive, high-speed and high-sensitivity. The experimentel results demonstrate that using this method to deal with fingerprints of low contrast also leads to satisfactory results, proving that the sensitivity of SD-OCT can be used for accurate and reliable patent fingerprint recognition.
