Why take this course?

The course introduces two important applications of optical systems: optical imaging and holography. Optical imaging and holography are widely used in areas such as physics, astronomy, chemistry, life The course introduces two important applications of optical systems: optical imaging and holography. Optical imaging and holography are widely used in areas such as physics, astronomy, chemistry, life sciences, and many disciplines of engineering. Many devices that are important for our daily life, such as smart phones, also rely on the principles of optical imaging for proper operation. The skills acquired in this course are highly relevant for many industries and research institutes. In this revision, we add optical imaging as an important application of optical systems. As a result, the discussion on optical beam propagation and holography has been reduced. The revised syllabus reflects this change. Level Justification: This course is suitable for 4000-level students, since it requires familiarity with the concepts of electromagnetic fields as covered in 3105. , and many disciplines of engineering.
