NCJRS Celebrates National Library Week April 12-18

National Library Week

Started in 1958, National Library Week is a nationwide observance celebrated by all types of libraries - including the NCJRS Virtual Library. NCJRS invites you to explore the breadth and scope of the NCJRS Virtual Library collection and services. With more than 220,000 collection documents and 60,000 online resources, including all known Office of Justice Programs works, it is one of the world’s largest criminal justice special collections.

We encourage your Feedback. Tell us how you use the NCJRS Virtual Library and Abstracts Database, how you access the collection, and any ways we can improve our services.

Title: Low Cost, Passive Sub-mm Wave Imager for Concealed Weapons Detection
Author(s): Michael Jack
Date Published: 2010
Page Count: 132
  Annotation: This research addresses the need for a low-cost and accurate sensor for detection and identification of concealed weapons under clothing at a range long enough for law enforcement to take appropriate action to eliminate any threat.
Abstract: The overall purpose of this program was to perform research and development on a concealed weapon detection system utilizing a modification of production worthy, uncooled infrared (IR) sensors to provide to law enforcement personnel an affordable, portable, covert, and passive imaging sensor of sufficient sensitivity and resolution to rapidly and accurately identify weapons, including. knives, guns, and explosives, at a “safe” range (15 meters). Under a previous contract with NIJ the authors identified an optimum submmW band (400GHz – 800GHz) which provided both good resolution while enabling good clothing penetration. The current program goals have been to: 1) optimize the detector design, incorporate the chosen design in a linear array, and integrate the array with a standard Readout Integrated Circuit, 2) evaluate submmW performance and detection of concealed weapons, and 3) provide a demonstrable submmW sensor as a laboratory prototype for evaluation by law enforcement personnel.
