In the precursor project “Insect Laser”, supported by the Federal Office for Agriculture and Food and partners, a solution was developed at Fraunhofer IZM to protect the agricultural stock from contamination by grain weevils and Indian meal moths. Though barely four millimeters long, these pests can cause significant economic damage and carry diseases.
It is common practice to fumigate storage spaces with chemicals only after an infestation with harmful insects. These chemicals, such as hydrogen phosphide, are deadly to the insects but can be used only sparingly. When used more frequently, residues on the stock can cause health hazards to humans and, above all, environmental pollution.
To reduce the use of chemical protective agents, the researchers at the Fraunhofer Institute for Reliability and Integration IZM set out to combine laser technology and automated image recognition to reliably ensure the safety of agricultural products. The project was coordinated by the Julius Kühn Institute in Berlin.
The researchers detect the moment of infestation before the pests can spread throughout the stocks. Using an image-processing method developed by the BTU Cottbus (Brandenburgische Technische Universität Cottbus), the small pests are detected on the surface of the supplies or on walls. An AI system then analyzes and classifies the insects and compares them against reference images. Such algorithms for image recognition are already established in countless applications. In this project, however, the wide variety of dimensions was especially challenging, since harmful insects that are only a few millimeters in size need to be reliably detected in the warehouses. This had to be taken into account in the design and production of the IZM laser system.
Once the position of a pest is known, a fine laser beam is directed to the relevant coordinates via radio by a scanner, rendering the corn weevil or Indian meal moth harmless. Because of the low temperature and intensity of the laser, the grains located underneath are unaffected. By using a laser system, direct primary infestation is prevented, so that insects harmful to supplies do not spread in the first place.
The Fraunhofer IZM researchers in Berlin examined how different wavelengths and light beam intensities influenced the movement behavior of the pests and found that the infrared light had the lowest effect on the characteristic movement behavior used to identify the animals. The researchers were also significantly involved in developing the laser system, and initially created a laboratory setup. Following successful testing, they transferred this set-up into a compact insect laser system consisting of several units for use in test cells.
They also developed the interfaces for software and hardware between camera, laser, and scanner.
With these activities, Fraunhofer IZM is opening up to projects that will increase digitalization and automation in agriculture. In doing so, the researchers integrate optical sensors and electronic controls into unique systems and ensure that these can be manufactured efficiently and used sustainably.

All three approaches - partly borrowed from astrophysics - are suitable for making statements about the chemical composition of a particle as well as visualising it. Raman spectroscopy take advantage of the fact that matter interacts with laser light, leaving behind a characteristic fingerprint - a spectrum in the scattered light. In this way it is also possible to assign the plastic particles to their original material - e.g. polyethylene, polystyrene or PVC. While this works well for sufficiently large pieces of plastic, the challenge for the team is to detect these fingerprints for small and minute particles. In addition, successfully scanning tissue samples with conventional Raman microscopes is very time-consuming and can take many hours to days. The innoFSPEC research centre at the AIP has set itself the goal of realising an imaging Raman spectroscopy setup that allows the identification of plastic particles within minutes or seconds. This is made possible by wide field spectrographs from astronomy - where this technique is used in observatories to save valuable observation time.
The joint project supports research at three Centres for Innovation Competence (ZIK) in the new federal states: ZIK plasmatis at the Leibniz Institute for Plasma Research and Technology Greifswald (INP), ZIK HIKE at the University Medical School and University of Greifswald and ZIK innoFSPEC at the Leibniz Institute for Astrophysics in Potsdam (AIP). The first results are expected to be available in two years' time in order to be able to better answer the question to what extent the contamination of the environment and thus of the human body with microplastic particles is one of the causes of neurodegenerative diseases, cardiovascular diseases or even cancer.

The key areas of research at the Leibniz Institute for Astrophysics Potsdam (AIP) are cosmic magnetic fields and extragalactic astrophysics. A considerable part of the institute's efforts aim at the development of research technology in the fields of spectroscopy, robotic telescopes, and e-science. The AIP is the successor of the Berlin Observatory founded in 1700 and of the Astrophysical Observatory of Potsdam founded in 1874. The latter was the world's first observatory to emphasize explicitly the research area of astrophysics. The AIP has been a member of the Leibniz Association since 1992.
The EU directive 2011/65/EU on the restriction of the use of certain hazardous substances in electrical and electronic equipment (RoHS 2) contains a list of chemical elements and compounds that may no longer be used in electronic products. This includes lead in concentrations above 0.1%. The legislators are primarily concerned with tin solder that contains lead. However, this heavy metal is also a crucial component in the PbS and PbSe detectors manufactured by the LASER COMPONENTS Detector Group.
Manufacturers can apply for exemptions from this rule if a product is indispensable for certain applications. Annex IV, point 1c of the directive explicitly mentions lead used in infrared detectors. Together with its customers, LASER COMPONENTS has formed a consortium that has been able to prove that an alternative to using lead salt detectors in certain areas is not available.
“Many SMEs would simply be overwhelmed with the burden of EU law if they tried to take it on themselves,” says Sven Schreiber, who coordinated the activities at LASER COMPONENTS. “As a well-known player in the international detector market, we have taken the initiative. We are confident that our application will be granted. This would benefit all market participants for another seven years. At that time, the exemption will be renewed.”
