INTRODUCTION
Till now the detection of concealed weapons is done by manual screening procedures.
To control the explosives in some places like airports, sensitive buildings, famous constructions etc.
But these manual screening procedures are not giving satisfactory results so we are need of a technology that almost detects the weapon by scanning. This can be achieved by imaging for concealed weapons.
IMAGING SENSORS
INFRARED IMAGER : Infrared imagers utilize the temperature distribution information of the target to form an image.
Ex : Night Vision Technology
CHALLENGES…!
One critical issue is the challenge of performing detection at a distance with high probability of detection and low probability of false alarm.
Yet another difficulty to be surmounted is forging portable multi-sensor instruments.
CONCLUSION
Imaging techniques based on a combination of sensor technologies and processing will potentially play a key role in addressing the concealed weapon detection problem.
Recent advances in MMW sensor technology have led to video-rate (30 frames/s) MMW cameras.
