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 AND THE CHARACTERISTICS OF OPTICAL RAYS
•THE RELEVANT OPTICAL COMPONENTS (LENSES, FILTERS, POLARIZERS, DIELECTRIC MIRRORS, OPTICAL MULTILAYERS, OPTICAL CAVITIES, GRATINGS)
•THE FUNDAMENTALS INTERFEROMETRY AND THE USE OF DIELECTRIC COATING IN HIGH-PERFORMANCE MIRRORS
•THE OPTICAL MATERIALS, OPTICAL CRYSTALS AND OPTICAL SENSORS
•THE FUNDAMENTALS OF RADIOMETRY, PHOTOMETRY AND COLORIMETRY
•THE FUNDAMENTALS OF OPHTALMOLOGY AND OPTOMETRICS


KNOWLEDGE AND UNDERSTANDING ABILITY TO APPLY (APPLYING KNOWLEDGE AND UNDERSTANDING)
AT THE END OF THE COURSE THE STUDENT WILL BE ABLE TO:
•USE THE GEOMETRICAL OPTICS TO BOTH DETERMINE THE CHARACTERISTIC PARAMETERS OF AN IMAGE-FORMING OPTICAL SYSTEM AND ANALYZE LIGTH PROPAGATION
•DESIGN ANTI-REFLECTION LAYERS, DIELECTRIC MIRRORS AND FILTERS
•RECOGNIZE THE APPLICATION FIELDS OF BOTH OPTICAL SENSORS AND COLORIMETRY
•RECOGNIZE THE APPLICATION FIELDS OF VISION AND OPHTALMOLOGY

MAKING JUDGMENTS
ABILITY TO IDENTIFY: A) THE DIFFERENT ELEMENTS OF A FIBER OPTICS TRANSMISSION SYSTEM; B) THE MOST APPROPRIATE OPTICAL FIBER/SENSOR FOR A SPECIFIC 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 KNOWLEDGE.

LEARNING SKILLS
THE STUDENT WILL BE ABLE TO DEEPEN THE TOPICS PRESENTED IN THE COURSE BY USING MULTIPLE SOURCES AND MATERIALS (ARTICLES ON MAGAZINES, JOURNALS, OTHER)

Verification of learning
TEACHING OBJECTIVES ARE CERTIFIED BY PASSING AN ORAL EXAM WITH AN EVALUATION OF THIRTY (THE MINIMUM LEVEL OF PASSING CORRESPONDS TO "18" AND THE MAXIMUM TO "30 E LODE") LASTING AVERAGE INDICATIVE OF 40 MINUTES. THE PURPOSE OF THE EXAM IS: 1) TO VERIFY THE LEARNING OF THE TOPICS COVERED IN THE COURSE; 2) TO CHECK THE ABILITY TO PRESENT THE TOPICS ADDRESSED; 3) TO VERIFY THE AUTONOMY OF JUDGMENT IN PROPOSING THE MOST APPROPRIATE APPROACH TO THE REQUESTED TOPIC.

THE EXAM CONSISTS OF THREE QUESTIONS EACH ON A TOPIC DEVELOPED IN THE COURSE (EXAMPLE: ELEMENTS AND CARDINAL POINTS OF AN OPTICAL SYSTEM, MODES OF PROPAGATION IN A STEP-INDEX OPTICAL FIBER, TRANSMISSION GRATINGS). DURING THE TEST THE STUDENT CAN USE A FORMULA-SHEET PROVIDED BY THE TEACHER.

TO PASS THE EXAM, IT IS NECESSARY TO REACH THE MINIMUM LEVEL OF EVALUATION IN THE PRESENTATION OF THE TOPICS REQUIRED IN ALL THREE QUESTIONS.

THE STUDENT REACHES THE LEVEL OF EXCELLENCE IF HE: A) ANSWERS THE QUESTIONS IN AN APPROPRIATE, CLEAR AND FLUID MANNER; B) ANSWERS FULLY AND PROMPTLY TO THE COMMENTS OF THE EXAMINING COMMISSION DURING THE PRESENTATION; C) DEMONSTRATES ABILITY TO MAKE CONNECTIONS BETWEEN THE THEORETICAL TOPICS TREATED; D) DEMONSTRATES FULL MASTERY OF THE TECHNICAL TERMINOLOGY.
