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: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Shape matters when light meets atom

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
