3D Optical Topography Podcast

Episode Three of Just Science, funded by the National Institute of Justice’s Forensic Technology Center of Excellence, features Dr. Ryan Lilien, from Cadre Forensics, and Todd Weller, from the Oakland Police Department talking about their groundbreaking research in optical topography and firearms identification.
