| Lehrinhalte | The course will be divided into 4 parts: 1. Regular Optical Microscopy In this first part, students will explore basic optical microscopy, a foundational technique for material analysis. Optical microscopy uses visible light to illuminate and magnify samples, providing real-time images of surface structures and defects. This method is valuable for examining grain boundaries, surface textures, and microstructural features in metals, polymers, ceramics, and composites. By understanding light-matter interactions and learning to interpret micrographs, students will gain skills essential for identifying physical properties and potential failure points in materials. 2. Regular Confocal Optical Profilometry Next, students will work with a confocal optical profilometer to achieve precise 3D surface imaging. Unlike traditional microscopy, this method measures height variations across a surface by using confocal optics, making it ideal for characterizing surface roughness, layer thickness, and topographical details. This is particularly relevant for surface engineering applications in materials where precision is critical, such as coatings and thin films. Students will learn how to visualize and quantify surface profiles, critical for understanding wear, corrosion resistance, and adhesion properties. 3. Fluorescence Confocal Microscopy In this section, students will engage with fluorescence confocal microscopy, which offers highly specific, in-depth visualization. This technique uses fluorescent labeling to highlight specific material features, allowing detailed analysis of composites, layered structures, and embedded materials. By using point-by-point scanning, fluorescence confocal microscopy provides fine resolution at different depths, revealing subsurface structures and even defects. Students will appreciate its applications in material quality control and advanced structural analysis where precise component mapping is required. 4. Femtosecond Pump-Probe Microscopy Finally, students will be introduced to femtosecond pump-probe microscopy, an advanced optical technique that uses ultra-short laser pulses to investigate dynamic material responses at the nanoscale. This technique is particularly powerful for studying rapid phenomena like thermal, mechanical, and electronic changes in materials, critical for high-performance materials like those in electronics or aerospace. By learning about pump-probe principles, students will understand how this tool can capture ultrafast processes, aiding in the development of materials with targeted properties. Each section will build practical skills and a solid theoretical foundation, equipping students with advanced microscopy knowledge applicable to a range of engineering challenges. |
