Airport scanners are designed to detect prohibited items and substances that are not allowed on planes, such as weapons, drugs, explosives, inorganic substances, and other metallic and non-metallic items. While older scanners could reveal naked images of passengers, newer scanners use advanced imaging technology (AIT) and millimeter wave scanners to detect a wide range of metallic and non-metallic threats without compromising privacy. These scanners can see through clothes and luggage to detect objects, but they do not show naked bodies and are designed to protect passenger identity.

What You'll Learn
X-ray scanners can detect metal objects in luggage
Airport security systems use metal detectors, backscatter X-ray machines, millimeter wave scanners, and cabinet X-ray machines to ensure the safety of people and luggage. These machines can detect metallic objects in luggage and on a person's body. X-ray machines are used to screen carry-on items and checked luggage. They release X-rays that pass through the luggage and calculate the mass and density of the contents.
While X-ray scanners can detect metal objects, they are also capable of identifying non-metallic objects and organic materials. They can distinguish between various substances by using X-rays that pass through different materials at different speeds. This allows security officers to identify items based on their density and atomic number. For example, plastic explosives or other contraband that could pose a threat to aircraft security can be detected through density and X-ray absorption.
X-ray scanners play a crucial role in ensuring the safety of air travel by meticulously inspecting the contents of travellers' luggage. They can detect a wide range of metallic and non-metallic threats in a matter of seconds. The identification process relies on the expert interpretation of X-ray images by trained security personnel, who are trained to spot visual signs of suspicious items and take appropriate action.

Scanners can detect organic materials like drugs, food, explosives
Airport scanners use advanced X-ray technology to detect threats and prevent dangerous items from being transported onto aircraft. They can see through dense materials to identify items based on their density and atomic number. This means they can distinguish between various substances, including organic materials like food, liquids, drugs, and explosives.
Different materials react differently to X-ray radiation, creating distinct images that trained operators can easily identify. Organic materials like food or explosives appear orange on the monitor, while metallic objects show up as blue or green, depending on their density. This enhanced detection capability makes it easier for security personnel to identify prohibited items or suspicious objects in baggage.
While scanners cannot directly identify drugs or explosives, they can provide visual hints that may indicate their presence. For example, unusual shapes or organic masses in luggage that don't match other packed items, unusually dense items on an X-ray image, or suspiciously wrapped packages that don't resemble typical travel items. Security officers are trained to spot these signs and can take further action or use specialized equipment if they suspect illegal substances.
In addition to detecting organic materials, airport scanners can also detect metallic and non-metallic objects, liquids, and even gold, as it is a metallic object with low conductivity. They can also detect items concealed under clothing and layers, including sweat, which can sometimes trigger false alarms. Overall, these scanners play a crucial role in ensuring the safety and security of air travel.

Millimeter-wave scanners can detect metal objects on the body
Airport security systems use metal detectors, backscatter X-ray machines, millimetre-wave scanners, and cabinet X-ray machines to ensure the safety of travellers. Metal detectors use magnetic fields to identify metal objects.
Millimetre-wave scanners are whole-body imaging devices used to detect objects hidden underneath clothing. They use electromagnetic radiation to create a three-dimensional image of the body, which is displayed on a remote monitor for analysis. The millimetre-wave scanner is distinct from a metal detector, as it can detect both metallic and non-metallic objects.
The millimetre-wave scanner directs millimetre-wave energy at the subject, which then reflects back and is interpreted by the machine. The wave energy reflects off the skin and other objects on the body, creating a detailed image. The technology can detect liquids, gels, plastics, powders, metals, ceramics, explosives, drugs, and money.
The millimetre-wave scanner is also capable of detecting metal objects on the body. The scanner's wave energy reflects off metal objects, creating an image that can be analysed by security personnel. This technology is particularly useful for detecting weapons, such as guns or knives, that may be hidden on a person's body.
While millimetre-wave scanners are effective at detecting metal objects, there have been concerns about privacy and the potential for strangers to view intimate details. To address this, the U.S. Congress prohibited the display of detailed images and required that metal and other objects be shown on a generic body outline.

Scanners cannot see through dense metal objects
Airport scanners use different technologies to screen passengers and their luggage. The two primary types of scanners are X-ray scanners and millimetre-wave scanners.
X-ray scanners are typically used for scanning luggage. They use low-level X-rays to create images of the contents inside bags. Metal objects appear clearly on the scanner's screen, often highlighted in a distinct colour such as blue or orange. However, X-ray scanners cannot see through dense metal objects. Instead, these objects appear as opaque or dark areas on the X-ray image, indicating the presence of metal and prompting further inspection by security personnel.
Millimetre-wave scanners are used for scanning passengers. They use non-ionising electromagnetic waves to create a 3D image of the body. These waves penetrate clothing but are reflected by the skin and any concealed objects, including metal. The waves are reflected by metal, creating an image of the object's outline. Security personnel can then determine if further inspection is required.
While airport scanners are highly effective at detecting metal objects, they cannot see through dense metal. This limitation is important for safety and compliance with international aviation regulations.
Overall, airport scanners play a crucial role in maintaining the safety and security of air travel by detecting prohibited and dangerous items.

Scanners can detect anomalies in simulated images
Airport scanners use X-rays to penetrate objects and detect a wide range of metallic and non-metallic items. They can also detect organic materials such as drugs, food, explosives, and paper, which are marked with orange colour. However, they cannot directly detect drugs hidden inside luggage. Instead, they rely on simulated images, where customs officers can identify anomalies to ensure safety and prevent illegal activities.
To train a machine learning model for anomaly detection, a dataset containing both "good" and "anomalous" images is required. The “good” images are used for training the model, while the test set includes both types of images to evaluate the model's performance. This process allows the model to learn the standard patterns and identify deviations or anomalies in new input images.
Additionally, techniques like Computer Vision and scikit-learn machine learning library can be employed to build a system that can automatically recognize anomalies. This technology has been applied in various fields, including manufacturing, surveillance, and medicine, to detect defects, identify suspicious activity, and diagnose medical conditions.
Overall, the ability of scanners to detect anomalies in simulated images is a crucial aspect of ensuring safety and security in airports, as well as in various other industries.
