Objectives
THE COURSE PROVIDES THE THEORETICAL ISSUES OF THE OPTICAL PROPAGATION AND DESCRIBES THE RELEVANT OPTICAL APPLICATIONS IN TELECOMMUNICATIONS (OPTICAL FIBERS, OPTICAL COMPONENTS AND SYSTEMS), IN SENSORS AND IN ANALYSIS AND MEASUREMENT SYSTEMS.

KNOWLEDGE AND UNDERSTANDING
AT THE END OF THE COURSE THE STUDENT WILL KNOWN:
•THE GEOMETRICAL OPTICS APPROXIMATION
•THE MODAL ANALYSIS OF OPTICAL FIBERS AND OPTICAL WAVEGUIDES
•THE OPTICAL FIBERS FOR TELECOMMUNICATIONS AND THE FIBERS FOR OTHER APPLICATIONS
•THE OPTICAL CHARACTERISTICS OF MATERIALS
•THE OPTICAL PROPAGATION IN CRYSTALS
•THE SCALAR DIFFRACTION
•THE FUNDAMENTALS OF RADIOMETRY, PHOTOMETRY AND COLORIMETRY

KNOWLEDGE AND UNDERSTANDING ABILITY TO APPLY (APPLYING KNOWLEDGE AND UNDERSTANDING)
AT THE END OF THE COURSE THE STUDENT WILL BE ABLE TO:
•DETERMINE THE CHARACTERISTIC PARAMETERS OF AN OPTICAL SYSTEM FOR IMAGING
•CLASSIFY THE OPTICAL FIBERS FOR THEIR PHYSICAL CHARACTERISTICS AND THEIR PROPAGATION REGIME


MAKING JUDGMENTS
ABILITY TO IDENTIFY THE MOST APPROPRIATE OPTICAL FIBER FOR A PARTICULAR APPLICATION


COMMUNICATION SKILLS
THE STUDENT WILL BE ABLE TO ILLUSTRATE IN A CLEAR AND CONCISE WRITTEN AND ORAL FORM, AND WITH THE CORRECT TERMINOLOGY THE ACQUIRED KNOWLEDGES.

LEARNING SKILLS
THE STUDENT WILL BE ABLE TO DEEPEN THE TOPICS PRESENTED IN THE COURSE BY USING MULTIPLE SOURCES AND MATERIALS
