The theme is physical optics, taught in contexts of physics, electromagnetic fields, optical engineering and technology, and photonics.
This unit illuminates electromagnetic waves in media, Fresnel reflection coefficients, multilayer dielectric filters, Gaussian beams, anisotropic media, non-linear optics, interference, the Fabry-Perot interferometer, Fourier theory, diffraction theory, Fraunhofer (far-field) diffraction, Fresnel (near-field) diffraction, spatial coherence, temporal coherence, optical transfer functions, the Abbe theory of image formation, holography, and modern aspects of near-field optics and their applications in measuring nanoscale phenomena.
