Syllabus: Geometrical optics: matrix formulation for lens, mirrors and combinations under paraxial approximation, image formation; brief introduction to primary monochromatic aberrations and chromatic aberrations. Diffraction: Fresnel and Fraunhoffer diffraction: rectangular and circular aperture; Lens as a Fourier transforming tool, spatial frequency filtering and Image processing; working principle of holography. Interference: Two and Multiple beam interference, Michelson and Fabry-Perot interferometer; line width and coherence; multilayer thin films as antireflection coatings. Polarization: linear and elliptically polarized light, Poincare representation; Jones vector: polarisers and retarders; production of polarized light: polarization by reflection, scattering, and selective absorption; birefringence, anisotropic media, optics of liquid crystals; optical activity, principles of magneto-optics, electro- optics and acousto-optics.
