Summary of Content

The aim of this course is to provide the student with a foundation in advanced optical and laser based instrumentation which will cover a wide range of topics in photonics and laser based instrumentation. This is a useful module for students who are looking for a job in industry or preparing for research in optical instrumentation and laser . The major objectives of the course is to provide the undergraduate students with the knowledge of a broad range of topics in optics, optoelectronics, optical technology, and laser based instrumentation and prepare the students for graduate studies or for an industrial job in optical instrumentation and laser based instrumentation.

Learning Outcomes

On completion of this module the student should be able to:1. Summarise the key concepts in optics, optoelectronics, and optical technology and their relevance in science and technology.(AM1)2. Interpret interference, diffraction, and polarization phenomena.(AM1)3. Distinguish the different types of optical sources and their application in instrumentation systems.(AM1)4. Explain various spectral methods of analysis and their practical applications in biomedical and chemical instrumentations.(AM5)5. Recommend suitable lasers for applications in medical and industrial fields. (AM5)

Teaching / Learning Strategy

The main teaching method will be based on lectures. The students will be expected to perform directed reading exercises and self-learning exercises on emerging technologies. Tutorials will be used to reinforce the module material discussed during lecture sessions. Tutorials also serve as a platform of technical discussions to clarify any queries that arise from directed studies.
