How Do Millimeter Wave Scanners Work?

The mechanism of millimeter wave scanners revolves around the use of low energy millimeter waves or radio waves. As per the following steps, the process provides a detailed, holistic image of the scanned object:

1. Emission of Waves: The scanner firstly emits these waves towards the object or person to be scanned.

2. Reflective Action: The transmitted waves have the ability to penetrate clothing and reflect off skin and other objects.

3. Collection of Waves: The reflected waves are gathered by the scanner's antennas for further processing.

4. Processing of Waves: The collected waves move down a guide into the scanner's receiver for processing.

5. Construction of Image: The processed data is utilized to construct an image, which illustrates precise information about the object — including its shape, size, and materials involved.

Apart from the standard operation, millimeter wave scanners can function in two types:

- Passive Scanners: They identify the natural emissions of millimeter wave lengths from the person or hidden objects.

- Active Scanners: They initiate the transmission of millimeter waves towards the body or object to be scanned and decode the reflected waves to construct the image.

What Can Millimeter Wave Scanners Detect?

Equipped with comprehensive detection abilities, millimeter wave scanners can identify a broad array of concealed objects. Facilitating the detection of both non-metallic and metallic items, their versatility makes them a beneficial asset in multiple fields. Let's have a look at the precise detection capabilities of these groundbreaking scanners:
