Why X-ray baggage scanner can recognize the items?
When the baggage enters the X-ray baggage scanner, it blocks the package detection sensor and sends the detection signal to the system control section to generate an X-ray trigger signal, emitting the X-ray from the source. As the X-ray beam penetrates every target object on the conveyor belt of X-ray baggage scanner, the radiation gets absorbed by the object, followed by the bombardment of the semiconductor detector mounted in the channel. The semiconductor detector converts the X-rays into signals, getting amplified, and transfers to the signal processing frame for more processing. These signals are finally processed and then displayed on the screen. Even if there are many layers in the baggage, X-rays can penetrate and show the contents of the baggage layer by layer.
A conveyor belt transfers each item towards X-ray baggage scanner. X-rays are electromagnetic waves with high energy, compared to light. Hence, they can penetrate through any material. The X-ray baggage scanner used in airports is usually based on a dual view X-ray system. This system has one X-ray source emitting X-rays in the range of 140 to 160kilovolt peak. KVP denotes the quantity of penetration an X-ray makes. The higher the KVP, the further will be the penetrating power of X-rays. After passing through the items under X-rays, the images are captured by a detector. This detector then transfers the X-rays onto a filter, which blocks the lower-energy X-rays. The resultant high-energy X-rays hit the second detector.

The angle of X-ray baggage scanner determines the shape of the inspected object: The angle refers to the angle at which the object to be inspected is placed in the X-ray baggage scanner. The shape refers to the shape displayed on the X-ray baggage scanner display screen. Since X-rays penetrate the object to be inspected, a flat image is displayed on the fluorescent screen instead of a stereo image, so we can easily cause misjudgments during the check-in process. When we conduct security checks, we should place the items flat on the conveyor belt of the X-ray baggage scanner. Because this is the best placement angle, X-rays can penetrate vertically, which is easy to identify.
The distance determines the size of the inspected object: Distance refers to the distance between the object to be inspected and the radioactive source. The closer the object is to the radioactive source, the larger the image.
Brightness shows the density of the object to be inspected. Brightness refers to the degree of brightness displayed by the fluorescent screen. Substances with different densities will have different display in the image. Substances with high density will absorb more X-rays and the image will be brighter. Inorganic materials have high density and display black images on the fluorescent screen.
Why we need X-ray baggage scanner?
When it comes to X-ray baggage scanner, I believe that it should be familiar to many people. When we are in stations or shopping malls, we often encounter X-ray baggage scanner. The X-ray baggage scanner is mainly a device to detect whether personnel are carrying some prohibited metal objects or contraband items.

With the development of society and economy, people's safety awareness is constantly improving. In order to provide people with a better safety environment, it is necessary to install the X-ray baggage scanner to detect some prohibited items so as to better protect people's lives and property.
The installation of the X-ray baggage scanner can play a very good preventive role so as to prevent people from danger. X-ray baggage scanner can better improve the safety index of some important places.
In recent years, more X-ray baggage scanners have been used by enterprises. Especially in various public places where we often come and go, X-ray baggage scanners are also used. But X-ray baggage scanner also makes many people worry about whether it is safe or whether there is radiation. It can be said that the X-ray baggage scanner provides people with a safety guarantee at any time, so that it can better play a role of safety precaution.
