CONTENTS
Period III During the lessons, the following chapters in Gåsvik "Optical metrology" are treated. In connection to the lessons a series of experiments are demonstrated, see the list below. Ch. Lessons: From Gåsvik 2nd ed. 1. Basics 3. Interference 4. Diffraction 6. Holography 7. Moire«techniques 8. Speckle methods 9. Photoelasticity and polarized light Demonstrations: 1. Diffraction, filtering etc 2. Schlieren and shadowgraph 3. TV-holography, shearography 4. Double pulsed holography 5. Speckle photography (ESP) 6. Moire«methods Laboratory work, period III: Two projects of 4 hours, one from each group A/B and C/D are performed. A. TV-holography and shearography B. Pulsed holographic interferometry. C. Electronic speckle photography (ESP) D. Laser doppler anemometry (LDA) A report is written for each project. This part of the course ends with a written examination of 4 hours. Period IV During the lessons, the following chapters in Gåsvik "Optical metrology" are treated. In connection to the lessons a series of experiments are shown, see the list below. Two invited lectures about fibre optics and optics construktion. Ch. Lessons: 5. Light sources and detectors 10. Digital Image processing 12. Some other optical metrology techniques. Appended papers: The computer as a measuring device Cases Analyses of data, IGOR Transmitters Demonstrations: 7. High speed cameras 8. The InfraRed (IR-)camera 9.
