Course content

Electromagnetic waves.
Geometrical optics. Matrix description of imaging systems. Aberrations. Wave optics and polarization. Optical waveguiding and fibre optics. Coherence, correlation, and interference. Fourier optics and diffraction. Introduction to optical imaging systems: human eye, camera, telescope, microscope. Introduction to optical spectroscopy, light sources and light detection.

Learning outcome

The student will get an introduction to the discipline of optics and its role in the modern society.

The student will learn to use the geometrical approximation, including Fermat's principle, the ray equation and paraxial matrix formalism for refractive and reflective surfaces. The student will be introduced to the design of optical systems and aberrations, with an emphasis on image forming systems.

The wave optics part of the course will give the student a thorough fundamental knowledge within interferometry, coherence, polarization and diffraction. The student will become able to analyze and understand interference between plane waves and spherical waves, reflection and transmission of plane waves, and optical wave guiding within thin plates and optical fibers. The student will get a thorough knowledge of the polarization of light and its changes upon reflection and transmission, and will learn to analyze the polarization in optical systems using the Jones formalism.

The student will get acquainted with Fresnel's and Fraunhofer's diffraction. The student will be able to calculate the diffraction from lattices, including the use of the convolution theorem for analyzing complex systems. The student will learn introductory Fourier optics and the wave description of image formation. The student will learn the connection between numerical aperture, F-number, spatial resolution and image quality for optical systems.

The student will be introduced to a range of different light sources including lasers. Finally, the student will get a thorough introduction to image forming systems with emphasis on the human eye, the camera, the telescope and the microscope.

Learning methods and activities

Lectures and demonstrations, calculations exercises, compulsory laboratory exercises. One compulsory hand-in/project might be given in analysis of an optical imaging system. The course might be given in English if international master students follow the course. If the course is given in English, the exam might be given only in English.

Compulsory assignments

  • Laboratory exercises

Further on evaluation

The re-sit examination (in August) may be changed from written to oral.

Specific conditions

Exam registration requires that class registration is approved in the same semester. Compulsory activities from previous semester may be approved by the department.

Course materials

Book: E. Hecht "Optics" - 5th ed. (Pearson; 2017).
