Computer scientists at Sheffield Hallam University, U.K., have developed a new face recognition software that can produce an exact 3D image of a face within 40 ms. A pattern of light is projected on a face, creating a 2D image, from which an accurate 3D representation is generated. In addition to security applications, the technology could be used to detect defects in products passing by on a conveyor belt. (www.sensorsmag.com/0706/RDScan)
