Microwave Imaging

Automated, damage-free screening of packaging

From the early detection of faulty parcels to the optimization of storage locations: In logistics, millimeter wave technology opens up new possibilities in quality assurance and inventory management. With this innovative technology, we offer precise detection of content, structures, and potential anomalies in real time.

  • Non-destructive screening

    Microwave imaging inspects packaging from the outside - it is completely contactless, without opening or damaging materials

  • Reliable under real logistics conditions

    Resistant to environmental influences: Functional in dust, smoke, fog, rain, or hail

  • Innovative & safe vision technology

    New, scalable vision technology with many application areas, safe and harmless for humans

  • Detection of overlapping and concealed objects

    For error-free packaging inspection - even with complex, multi-layered or confusing contents

How does microwave imaging work?

A technology that can see through fog, fabrics, and even walls: Microwave Imaging uses microwave radiation. This produces non-invasive and safe images that provide deeper insights into internal structures. The system's camera converts the signals received from the microwave sensor into digital images. This provides the user with clear representation of the internal structures of objects.

Microwave imaging technology through the transmission and reception of millimeter waves
The length of millimeter waves lies between that of light and that of radio waves

Millimeter waves for scanning objects

Unlike conventional cameras, microwave imaging technology works by emitting and receiving millimeter waves. The length of these millimeter waves lies between that of light and that of radio waves. They therefore have a combination of the properties of these two waves: They are invisible to the human eye, but propagate like light in a straight line in all directions. This allows us to look insidepackaging to detect hidden objects or anomalies - safely and non-destructively.

Short-wave infrared light (SWIR) is absorbed or reflected by many materials, but when microwaves are used, many objects are penetrated more deeply: Plastic, wood, cardboard, and fabrics are transparent to these waves, so structures behind them become visible. Metals are the only reflective material.

Compared to X-rays , microwave imaging is harmless and can be used without a permit. This makes it particularly well suited for use in industries where speed and safety are crucial.

The system set-up

With millimeter wave technology, an object is illuminated by a mm-wave transmitter. The reflected rays are then recorded by the camera using a sensor array: This is a combination of different sensors in one module, which take certain measurements simultaneously.

Non-destructive screening of packaging

Our microwave imaging system creates clear, unambiguous images of the inside of packaged products - without opening or damaging the material. Ideal for automated inspection processes in logistics.

  • Harmless and healthy electromagnetic waves for people and the environment

  • Insensitive to difficult environmental conditions such as dust, smoke, rain, fog, hail, bright sunlight, and extreme temperatures

Typical application areas for millimeter waves in logistics

Millimeter wave technology is used in logistics to improve the efficiency and security of supply chains. It enables the detection of objects and the identification of damage. Contents can be checked in parcels without opening them - which contributes to theft prevention and process optimization.

Quality control & prevention

The system automatically detects damaged objects in the parcel, as well as moisture or liquids.

Warehouse management & accuracy

The system identifies and counts the objects in a closed package and recognizes empty spaces.

Integrity of the supply chain

The system ensures secure supply chains and protects against theft, e.g. by exchanging objects.

Security & Compliance

The system detects unauthorized objects. Security guidelines are adhered to, and checks are carried out without opening the packages.

What does innovation project mean? 

We are currently looking for partner companies with whom we can jointly validate use cases and implement initial pilot projects. If you have a suitable use case, please contact us.

As a project in the innovation phase, we are concentrating on using our customers' experiences to see how well mm-wave imaging can be used in real applications and which use cases are generally possible

To do this, we want to understand the specific needs and challenges of your application. Based on your feedback, we can move our project forward! 

We look forward to you joining the development project!
