Learning objectives
This laboratory course is aimed at introducing the students to the experimental study of fundamentals of Optics, with particular attention to Fourier Optics. Starting from the elementary principles of radiation emission from ordered systems, the students are brought to study experimentally all the Fourier Transform theorems through simple laboratory experiments.
Expected learning outcomes
At the end of the laboratory course the student will be able to:
· Align an optical system of intermediate complexity
· Shaping a laser beam with proper spatial features
· Analyze an optical system dealing with the fundamentals of geometric and Fourier Optics
· Analyze a problem through the Fourier Optics theorems
· Describe, design and realize a simple imaging system
· Describe, design and realize a simple diffraction system
· Work on problems deealing with the detection and characterization of wavefronts modulated in amplitude and/or phase
· Read the main Optics textbooks, even in English
Course syllabus and organization

Single session

Lesson period
Second semester
The course will be delivered entirely remotely in case of travel
restrictions due to Covid-19. In this case, the lectures will be offered
in virtual classrooms (zoom platform) in synchronous connection, with the
possibility of real-time interaction between the students and the teacher. Activities will be specifically adpted to allow students to perform experiments "at home", achieving the same objectives obtainable in labroatory.
