INTERFERENCES

Two-wave interferences
Interference Conditions : introduction to spatial and temporal coherence.
Spatial separation interferometers.
Luminance (beam) separation interferometers : localisation surface, Michelson interferometer, Twyman Green variant, Mach-Zehnder.
Main light sources : coherence lengths (in relation with Fourier Transform spectroscopy)
Multiple wave interferences : Stationary waves and Lippmann color process ; Fabry-Pérot interferometers, applications to spectroscopy.

DIFFRACTION
Huygens-Fresnel principle : formulation and analytical expression.
Fresnel vs. Fraunhofer diffraction regimes.
Coherent Illumination imaging, applications to filtering of spatial frequencies, Coherent modulation transfer function (CMTF)
Diffraction gratings, accessible orders, blaze & stigmatism.
