Summary
The aim of this course is to acquaint students with the use of optical fibers not only as a communication medium but also as a element suitable for sensory use. Students are familiar with the differences between communication and sensory fibers, division of fiber optic sensors, futhermore with the basic characteristics, principles and processes, which are using in these fibers for the sensory operation and also with practical applications of these sensors.
Compulsory literature:
Recommended literature:
Krohn, D. A.: Fiber Optic Sensors - Fundamentals and Applications. 1992
Way of continuous check of knowledge in the course of semester
During semestr students must attend 2 tests and elaborate 6 protocols from measurements. Minimal passing points for semester part is 20 point, maximal then 40.
Examination is combined (written for 50 points and oral for 10 points).
