Sammanfattning : The eddy current method is used for nondestructive evaluation of conducting materials. To achieve a greater knowledge and insure safe and reliable evaluation methods, the use of mathematical models and simulations are needed. LÄS MER
3. Detection and 3-D positioning of small defects using digital radiography, 3-D point reconstruction, and tracking
Sammanfattning : The weight and quality concerned aero industry is constantly trying to decrease the excess material in their components. With decreased weight the fuel consumption can be lowered and the negative environmental effects from aviation decreased. LÄS MER
4. Photonic THz Generation and Quasioptical Integration for Imaging Applications
Sammanfattning : This thesis deals with the analysis and optimisation of the uni-travelling-carrier photodiode (UTC-PD) for continuous-wave generation in terahertz (THz) frequencyrange. Photonic THz generation using UTC-PDs is extremely promising as it offers wide tunability, adequate output power and room temperature operation. LÄS MER
5. Reduction of material noise in ultrasonic nondestructive evaluation using synthetic frequency diversity algorithms
