20810065-2 - OPTICS

The course provides the tools to treat diffraction and propagation of coherent and partially coherent light fields. In particular, the problem of light propagation in paraxial conditions is addressed, which formally corresponds to the evolution of the wave function of a quantum particle in two dimensions. Techniques are also introduced to address the study of the non-deterministic fields. Some applications based on diffraction phenomena, such as diffractive optics and holography, for the unconventional manipulation of light fields are also presented.
