Examine various aspects of geometric and wave optics: - Geometric optics: thin lenses, the concept of approximate stigmatism, depth of field, vision of the eye (accommodation, etc.). Possibility of combining multiple lenses, an eye... - Wave optics: from the concept of path difference (for senior year students) to the effects of a glass plate, the concept of coherence length..., in various situations: infinitely narrow or wide Young’s slits or holes, freely movable sources to recreate a Michelson interferometer, a diffraction grating, a Lloyd mirror, using either a monochromatic source or white light.
