Stokes Image Sensor for Non-Invasive and Rapid Latent Fingerprint Detection
Abstract
This project developed a portable system that can rapidly capture a latent fingerprint without disturbing the site. This system uses an optical technique to image latent prints using spatially resolved polarization phase shifts of a probe laser. This is a two-phase effort that includes a proof-of-principle experiment followed by the development of an operational prototype. The primary output of this effort is the ability to collect latent prints without traditional powders. This latent print capability enables investigators to identify an individual frequenting a particular location, without alerting the individual to DoD’s ongoing investigation by leaving powder residue at the scene.
