With High-Speed-Microscopy, large-area objects can be acquired in a very short time on a microscopic scale. In industries such as semiconductors, electronics and biology, the demand for microscopic inspection methods is particularly high, as the increasing inspection of large surfaces requires an ever faster acquisition process.
In contrast to conventional stop-and-go operation, high-speed microscopy allows the object to move continuously during the recording process. This allows the sample to be digitized at very high frame rates - more than 500 fps depending on the camera. Synchronous flash illumination avoids motion blur. During the continuous scanning process, real-time hardware autofocus systems automatically adjust the focus so that the sample is sharply imaged at any point.
The Fraunhofer IPT is working on accelerating the acquisition process even further and regularly selects new components for fast image acquisition, such as lighting, sensors for hardware autofocus systems and camera technology.
Software for real-time data recording with RAM recording, which was developed at the Fraunhofer IPT specifically for high-speed microscopy, ensures that image pre-processing and stitching run without delay thanks to GPU processing. Generated large-scale images can be evaluated with specially developed image processing algorithms. Actual developments aim at the use of machine learning methods like Deep Learning and Convolutional Neuronal Networks (CNN).
