Anyone who has traveled by air in the past 10 years will know how stressful airports can be.
You didn't leave home as early as you should have. In the mad rush to get to your gate, the security screening seems to slow everything down. And to add insult to injury, you're met with the finicky request: "Laptops out of bags, please."Before 9/11, you could pass through security with a carry-on bag full of everything you might need for your vacation, including a knife with a four-inch blade.
The main reason you have to remove your laptop from your bag is because its battery and other mechanical components are too dense for X-rays to penetrate effectively, especially if the scanning system is old. The same goes for power cords and other devices such as tablets and cameras. With newer multi-view scanning technology, security officials can view the bag from multiple angles to discern whether something is being covered up, or made to look like something else. For instance, people have tried to mix gun parts with other components in an effort to pass checked baggage screening.
The larger body scanners, on the other hand, are a type of X-ray machine. These can be active or passive, or a combination of both. Another type of scanner emits lower-energy millimeter waves, instead of X-rays, to image the passenger. Millimeter wave frequencies are considered to be non-ionizing radiation.Artificial intelligence seems to be all around us lately, and our airports are no exception. Advancements in AI systems stand to transform the future of airport security.
