Le programme
Principle and operation of an interferometer, coherence and applications
- Analysis of 2-beam interference and contrast losses, N-beam Interference
- Sub-systems of an interferometer (splitting, combining, [de]modulation), types (Young, Michelson, Mach-Zehnder, Fizeau...) and exploitation (Zernike polynomials)
- Detailed study of spatial and temporal coherence
- Interferometric techniques and uses (longitudinal or surface metrology, spectroscopy, velocimetry, fibered sensors, coherent detection, phased arrays)
- tutorial classes: part or prolongation of main course, study of application cases
Practical exercises
