The course "Fundamentals of Optical Measurements" introduces physical principles and applications of modern optical methods and instruments in the field of metrology and optical non-destructive testing. It gives a theoretical description of the phenomena and methods. The description of the experimental devices and practical examples of their use follows.
Students will acquire the basic knowledge of the principles of modern and classical optical methods, their applications and possibilities of use. Students will receive some practical skill to work with some fundamental methods and devices. Students will be able to design optical measurements and to use of optical instruments actively.
