Ultra fast 100 percent examination under the microscope

11.11.2015

Large-scale components with tiny details often have to be examined under the microscope for quality control. The demand for microscopic test methods is particularly high in the semi-conductor and electronics industry due to the high degree of miniaturization. However, the recording process is very tedious when examining large objects microscopically, because thousands of individual photos must be taken and analyzed. From 10. to 13. November 2015, Fraunhofer IPT is presenting a new recording process, with which large-scale objects can be examined under the microscope in a matter of seconds, at the electronics trade fair “Productronica”.

High-Speed-Microscopy for quality control

Traditional recording processes for large components with high magnification often take so long that 100 percent examinations cannot be performed due to a lack of time meaning that only random samples can be examined.

After all, the number of photos and therefore the time required depend on the magnification used in microscopy: the large-scale component must be precisely positioned with the sample table before the individual photos can be produced and analyzed.

Fraunhofer IPT has now developed a new recording process, with which large-scale components can be examined under the microscope in just a few seconds: the table moves the object continually during the recording procedure, in contrast to the conventional “Stop-and-Go” operation.

This allows the sample to be digitalized with very high image rates – with more than 100 frames per second depending on the camera. Due to the fact that the object is only exposed extremely briefly with a flash, the photo is also free of any motion blur.

During the continuous scanning process, the focus is readjusted using real-time-capable hardware autofocus systems so that the sample is displayed with a sharp focus at all points.

High-performance data and image processing

The time-optimized scanning process is combined with real-time-capable data handling and image preprocessing stages. Even intensive computing steps such as stitching processes run almost without delay thanks to GPU support.

Automated image processing work for quality control can already be carried out parallel to the scan, so that the results of the examination process are available immediately after the high-speed scanning process.

This new system is the first to allow a successful 100 percent microscopic examination that can keep up with the rapid speed of industrial production.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
