Understanding Millimeter Wave Technology
Millimeter wave technology operates in the frequency range of 30 GHz to 300 GHz, corresponding to wavelengths between 1 millimeter and 10 millimeters. This range allows it to detect and image objects that are not easily visible to conventional imaging techniques such as X-rays or visible light.
How Millimeter Wave Imaging Works
The operation of millimeter wave imaging technology can be broken down into several key components:
1. Emission of Millimeter Waves: A source emits millimeter waves that interact with the target object.
2. Reflected Waves: The waves bounce back from the object, carrying information about its size, shape, and material properties.
3. Detection: Specialized sensors capture the reflected waves and convert them into electrical signals.
4. Image Reconstruction: Advanced algorithms process the electrical signals to create an image that reveals the structure of the object.
This sophisticated imaging technique allows operators to detect concealed items, determine material composition, and assess structural integrity without direct contact.
