In order to provide such an experience, what the security junctions need is short, fast-moving queues and the scope of detecting all the items within the scanner, eliminating the need for rummaging through baggage.
Today’s standard baggage scanners use the approach of X-Ray imaging, similar to one that the doctors use in order to detect fractures.
Such scanners work by extending ray towards the object which then penetrates through it and measures how much energy is coming back in return. This forms something like a shadow.
It is the different shapes and degrees of these shadows that determine the various items.
Unfortunately, shadows are not always what they seem to be. There are still many items that are hard to detect using the normal X-Ray scanners as it would require high-level computer processing that the scanners may not be able to handle.
The need-of-the-hour is a device that is competent enough to detect and determine the threat-status of the objects being scanned by itself while maintaining a high-speed level.
That is why a new range of advanced scanners are being introduced in the market. These scanners use technology such as computed tomography to integrate the X-Ray mediation images from various viewpoints and result in a 3D shape of the object.
It has been already introduced and used by the authorities, providing them and the passengers with many advantages (how we do not have to take out electronic items such laptops and iPads from our bags anymore).
This system has been working perfectly in identifying shape-based threats such as guns and knives. Such transmission X-Ray scanners routinely identify objects. The modern improvements such as deep learning-based image recognition algorithms enable automated recognition of a variety of threat objects.
