Researchers at the National Institute of Standards and Technology have demonstrated a laser-based imaging system that creates high-definition 3D maps of surfaces from as far away as 10.5 meters. The method may be useful in diverse fields, including precision machining and assembly, as well as in forensics.
Ed Graf has spent 25 years in prison in Waco, Texas, convicted of setting a fire in a shed that killed his two stepsons.
