Physical Basics of Non-Destructive Testing and Imaging |
| Description |
PREREQUISITES
A successful passing of the courses of the MSc Precision Engineering Basic Courses «Introduction to Materials and Analytics», «Introduction to Ultraprecision Engineering» and «Introduction to Precision Optics» is strongly recommended.
COURSE DESCRIPTION
This course will give physical basics of different non-destructing testing and imaging techniques with a focus on ultrasound, electron– and X-ray-techniques.
1. Physical Basics
1.1 Relation between physical and structural properties
• Types of ultrasound waves: longitudinal compressional, transversal shear, longitudinal shear, surface waves
• Coupling between different types of waves
• Interaction of ultrasound with acoustic properties: reflection/transmission, refraction, diffraction, random scattering, absorption
• Interaction of electromagnetic waves (e-beam, X-rays) with the electron density of materials: reflection/transmission, diffraction, refraction, diffuse scattering, absorption
1.2 Measurement techniques
• Introduction into different X-ray techniques
• Echo ultrasound
• Through-transmission ultrasound
• Monochromatization of the X-ray beam
• Filters and absorbers
• Beam shaping modalities
1.3 Ultrasound transducer types
• Piezoelectric transducers
• Air-coupled transducers
• Electromagnetic transducers
• Laser ultrasound
1.4 Diffractometer design
• Requirements and resolution
1.5 Signal Analysis/ Data Handling
• Fourier transform
• Monostatic and multistatic imaging, physical and synthetic focusing
• The reciprocal space
2. Application Examples and Fields
2.1 Ultrasound
• Testing of welds, thickness, material properties
• Medical ultrasound imaging
• Seismic imaging
2.2 Electron emission
• SEM
• TEM
2.3 X-Ray
• Scattering theory (coherent and non-coherent scattering)
• SAXS
• CT Imaging
• Reflectometry
• Diffraction theory |
