Everyone is fascinated by the idea of travelling all over the world. Travelling is such a pleasure and helps in gaining knowledge. While travelling, you get to meet a lot of people from different countries and different cultures. The idea of travelling is a lot of fun for most of the people. Also, travelling in an aeroplane saves time. Everyone loves to travel to in an aeroplane but the thought of waiting in long queues for security check is tiring. People are advised to reach the airport in time for the security check. Just imagine how amazing it would have been with no waiting in long queues. That would have made travelling a lot easier. Luckily, the researchers at Northeastern University are working to make airport security check less tiring.
“The eventual goal is to have hallways with sensors on the left and right sides. You walk between them and as you walk by, the sensors will create an image of your body,” says Carey Rappaport, College of Engineering Distinguished Professor at Northeastern University.
The researchers are working to devise such a scanning system which manages to get a 360-degree view of the person without the need to scan every side of the person. The sensors which are currently in use at the airport send out some radio waves which can be used to create an image of the person. These waves are known to penetrate clothing and bounce off the skin. The radio waves which are reflected are known to create an image while those which do not reflect cannot be sensed by the sensors.
“Unless you have a receiver in the right direction, you won’t be able to image that part of a person,” says Jose Martinez-Lorenzo, an associate professor of engineering.
Rappaport and Martinez, along with a post-doctoral researcher at the Northeastern University Borja Gonzales-Valdez, thought of installing link on sensors on the opposite wall to catch the reflected waves and form a complete picture.
“The waves bounce off your stomach or your back and end up on the other side of the hallway. So put detectors on both sides. Put a transmitter on the right, and observe right and left. Put a transmitter on the left, and observe left and right. That’s it. That’s the way you could get the front of a person, and you don’t have to have him or her turning to face the wall or pirouetting around,” explained Rappaport.
This technique would help a lot of travellers to enjoy the luxury of an aeroplane without having to wait in the long queues. However, there are certain things to be taken care of regarding the technique. Hopefully, it would be in action soon.
