Course Description

By studying this course, we require students to understand the dual nature of wave and particle property of light, learn to use optical methods and optical information processing methods to deal with practical problems, and gain new perspectives on the understanding of physical problems. The course mainly describes the geometrical optics theory and wave theory of light propagation which includes Fermat principle, light equation, Huygens-Fresnel principle, Fresnel-Kirchhoff diffraction integral, reflection and refraction of light at the interface, and propagation of light in anisotropic media; The course also contains statistical properties of light field which includes temporal coherence and spatial coherence of light field and polarization state; We will introduce some optical instruments and devices such as spherical mirror, thin lenses, ideal imaging system, microscope, telescope, split wavefront interference device, Fabry-Perot interferometer, grating spectrometer, Leo filter, optical information processing system, holography principle; Finally, we will discuss some knowledge about the basis of photometry and colorimetry and quantum property of light.
