Course Learning Outcomes:
By the end of this course, the student will understand:
- Waves and propagation: Definitions, variables, conventions, standing waves, traveling waves (longitudinal and transverse). Plane waves versus spherical waves.
- Maxwell’s equations, wave equation, Poynting vector and energy flow
- Polarization, dispersion, energy, momentum, dipoles, sources of polarization, propagation, equation of motion for bound electrons. Huygen’s principle, Snell’s law, reflection, transmission, refraction, Fresnel expressions, TIR, FTIR, Beer’s Law
- Geometrical Optics: diffraction limit, OPD, imaging, conjugates, ray tracing with thin lenses, compound lens ray tracing, aperture stops, field stops, pupils, marginal and chief ray, paraxial reduction, Lagrange invariant, matrix methods, thick lens treatment. Examples: telescopes, eyepieces, microscopes, etc.
- Aberration theory: chromatic versus monochromatic (geometry vs. image quality). Derivation of first and third-order monochromatic aberrations, Seidel coefficients.
- Superposition and coherence, polarization, polarizers, waveplates, birefringence, Jones matrices.
- Interference, fringes, visibility, interferometers-amplitude-splitting and wavefront-splitting (YDS, Michelson, TG, MZ, shear plate, …)
