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
• Michelson interferometer
• Fizeau interferometer (Zygo type)
• Homodyne/heterodyne detection (acousto-optic modulator)
• Speckle interferometry (deformation/vibration)
