COURSE AIM
To get the student familiar with the foundations of modern optical measuring methods and to apply these methods in measurements in combination with computers.

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.
