Description

This course is designed to: (i) To provide an appreciation of the fundamental concepts of wave optics. (ii) To illustrate the relevance of these concepts in modern applications of optics (iii) To develop numerical problem solving skills in wave optics The course is predominantly knowledge-based. The main learning activities are attending lectures and tutorials and the related learning activity of solving numerical and other problems related to the topics covered. Students are expected to attend lectures and tutorials and to prepare for both by appropriate study (including the use of on-line moodle resources provided and textbooks) and thus be able to engage fully in discussions and other interactions in lectures and tutorials. Students are further expected to prepare for in-class tests and end of module examinations via study and, as needed, discussion with the lecturer.

Learning Outcomes

1. Explain the essential physical aspects of the phenomena of wave polarization, interference, diffraction and lasers and optical cavities both qualitatively and mathematically, including the generation and manipulation of particular polarizations, interference by division of wavefront and amplitude, diffraction from various simple aperture configurations and lasing conditions
2. Discuss, both qualitatively and mathematically, optical information storage, image formation, and holography, and their linkages to other basic concepts in optics
3. Describe, both qualitatively and mathematically, examples of applications of interference, spatial filtering, lasers and optical cavities and practical holographic systems
