Laser Scanning Preserves Evidence

Newer to the forensics field is 3D laser scanning technology. These tools allow analysts to collect precise dimensions, blur moving face in video evidence and features to be recorded for later analysis. By capturing large amounts of data very quickly, 3D laser scanners allow investigators to capture a complete 360-degree image of a scene in minutes. The Trimble TX8 3D laser scanner, for example, captures up to 1 million points per second and can perform a typical high-density scan in about three minutes. " In a traditional crime scene, investigators identify all the evidence in the environment," Cognitech says. "Some...
