The "Secret" in the Security Checkpoint

To ensure flight safety, security checks are an important part of every passenger's journey on a civil aviation aircraft. This process is undoubtedly familiar to passengers—before entering the airport's restricted area, luggage must pass through security scanners, and passengers themselves must pass through security gates before undergoing a more thorough check by security personnel with handheld scanners.

In this process, the security gate acts as an important "safety barrier." So, what exactly are the functions of such a gate? And what are the future design and development trends for security gates? Researchers from the design team of the millimeter-wave 3D body scanning imaging security gate—the 35th Institute of the Third Academy of China Aerospace Science and Industry Corporation—explained the mysteries to reporters.

In recent years, security checks in China have become increasingly stringent, often sparking public discussion. The numerous restrictions imposed by security regulations can frustrate some passengers, while increasingly "transparent" security technologies can greatly annoy privacy-conscious passengers. While strict regulations "safeguard" aviation safety, how can passenger travel experience be maximized? Many airports are introducing and using new equipment and methods for security checks. The application of 3D scanning products is one such trend.
