Educational process provides studying of the following subjects:
Wave Optics (6 ECTS)
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 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 idea of moving media optics and measurement converters on this basis is presented.
Optical Systems and Components (5 ECTS)
Contains the basic data on the principles of design, calculation, working out and adjustment of various optical systems. The basic types of imaging optical systems (telescopes, microscopes, camera lenses etc.), their features and the general properties are considered. 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). Main types of optical components (plates, prisms, wedges, spherical and aspherical lenses) are described. The information about optical films and coatings is presented. Finally, the idea of optical design, production and testing routines is presented.
Laser Technique (5 ECTS)
