Synopsis:

This course gives an introductory into the optical sensors. The fundamental principles of absorption, luminescence and SPR sensors are discussed for a wide range of application.Course description:

First part of this course gives an introductory into theory of the electromagnetic field. Second part describes the wave phenomena in mechanics and electromagnetism. Third part is devoted to introduction into atomic physics.
