Given the security situation in Pakistan, there is urgent need of technology that will allow scanning of bodies for concealed weapens to be carried out from a distance. This will prevent criminals from coming too close with weapons concealed under their clothing. No such technology existed-till now!
The New York Police Department and the United States Department of Defence have been involved together in the development of remote sensing devices that will detect weapons remotely. The portable scanner relies on the infrared rays produced from the body. An image of these rays cab be detected by the scanner. If a weapon is present, then the infrared rays are blocked by the metal and a silhoutte of the weapon can be seen. The range of the equipment is being extended so that it can detect concealed weapons from a distance of 82 feet.
