Millimeter Wave Imaging Advances Industrial Quality Inspection
Rohde & Schwarz has introduced the R&S IMAGER, a real-time millimeter wave inspection system designed to enable non-destructive quality inspection of packaged products across pharmaceutical, logistics and manufacturing applications.
Using non-ionizing millimeter wave technology, the system can inspect products through common packaging materials without the use of X-rays, providing manufacturers with a safe method of verifying product integrity while protecting both operators and sensitive products. The technology generates high-contrast three-dimensional images that can be incorporated into AI-driven inspection systems for automated defect detection and quality assurance.
High-Speed Volumetric Inspection
The R&S IMAGER expands Rohde & Schwarz’s industrial inspection portfolio by combining millimeter wave imaging with advanced signal processing. The system transmits millimeter waves through packaging materials, analyses the reflected signals using a sensor array and reconstructs detailed volumetric images capable of revealing hidden components, assembly errors and material defects.
Unlike conventional vision systems, which are limited to surface inspection, the R&S IMAGER provides a three-dimensional digital representation of every inspected package, enabling manufacturers to verify internal product configuration at production-line speeds.
Pharmaceutical Manufacturing
The pharmaceutical industry is expected to be one of the primary beneficiaries of the technology. Because millimeter waves are non-ionizing, they do not alter or damage pharmaceutical products, making the system suitable for inspecting sterile medical devices and packaged medicines.
The technology can penetrate cardboard cartons, multilayer packaging and sealed containers to verify the presence and correct positioning of syringes, needles, autoinjectors and other medical components. AI-powered analysis of the resulting 3D images enables automated identification of missing, misplaced or incorrectly assembled components without reducing production throughput.
By providing complete inspection of packaged products, manufacturers can improve quality assurance, support regulatory compliance and reduce the risk of costly product recalls.
Logistics and Supply Chain Verification
The R&S IMAGER also addresses inspection challenges within logistics and distribution operations.
Conventional weight-based inspection and external vision systems cannot always verify that the correct product is contained within sealed packaging, while X-ray inspection may introduce additional safety and regulatory considerations.
Installed over conveyor systems, the R&S IMAGER continuously captures volumetric images of packaged goods, allowing AI algorithms to detect missing components, misplaced items or concealed damage in real time. The technology can improve inventory accuracy, reduce manual inspection and provide comprehensive digital records throughout the supply chain.
The ability to inspect products through a wide variety of packaging materials also supports manufacturers adopting more sustainable packaging solutions without compromising inspection capability.
Food and Beverage Inspection
In food and beverage production, the system provides non-contact inspection of sealed cartons, multipacks and glass containers.
Millimeter wave imaging enables manufacturers to detect missing products, damaged contents and sealing defects that are not visible externally. The technology can also identify subtle issues such as vacuum loss in sealed glass containers while production lines remain in operation.
Early identification of packaging defects helps manufacturers reduce waste, improve product quality and protect brand reputation, while the use of non-ionizing radiation ensures food quality remains unaffected.
Integrated AI Inspection
Designed for straightforward integration into existing production environments, the R&S IMAGER interfaces with production control and quality management software, allowing manufacturers to expand inspection capability without major modifications to existing production lines.
By combining volumetric imaging with artificial intelligence, the system represents a significant advance over conventional surface-based inspection techniques. As manufacturers face increasingly complex products, higher quality expectations and stricter regulatory requirements, the ability to inspect every packaged unit quickly and non-destructively offers an important advantage for modern production operations.
