Scientists have created an infrared body-scanner to help tackle surging violent crime rates. It combines a standard camera with infra-red technology to detect concealed blades from up to 20ft (6 metres) away and works through heavy clothing and even belts. The researchers are adapting cameras to detect infrared electromagnetic waves and feed their images into a special computer algorithm that can highlight the presence of weapons hidden underneath clothing. 'This technology may act as a deterrent and aid with knife crime detection, and maybe it has the potential to save lives.' Approaches being explored by the other funding recipients include the application of radar technology and acoustic sensors to detect hidden knives.
