Despite the advances made in areas such as DNA profiling, fingerprints are still considered to be the best form of personal identification 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.
