Physical basics of optical systems for data collection, storage, and transfer are presented. Primary attention is paid to the laws of light reflection, refraction, and propagation in isotropic and anisotropic media. Light propagation in optical fiber and the idea of the optical fiber communication systems are described on this basis. Light interference, as well as some of its applications (interference measurement converters, interference filters, and demultiplexers), are considered. The information on the optics of moving media and measurement converters on this basis is presented.

Basics of the theory of the optical image and aberrations are presented. The basic types of non-imaging optical systems – lighters, projectors, various types of interferometers are considered also, and also the basics of optical photometry are considered. The course also presents the basics of optical materials and technology, including the processes of glass fabrication and optical crystals growth, the idea of glass and crystal processing (cutting, grinding, polishing and finishing).
