About
:
Optics is used in many applications today. In fact, the field of optics has quietly gone from the research table to being used in numerous applications ranging from devices to metrology. Opto-electronics and metrology are already well-developed fields merging the areas of optics and a variety of other engineering areas (such as electronics, mechanical engineering, etc) in many advanced and commonly used devices. For an engineering student to be able to understand and design optics for such applications, it is important to understand some basic optics. This course will introduce these concepts at a level relevant for an engineer. The course will start by looking at Geometric optics, before moving on to Gaussian optics and then wave optics. The course will also study specific engineering examples with a detailed look at the optics of these. A lab will be run along with the course. In the first part, an optical design software called Optics Software for Layout and Optimization (OSLO) will be used. The ideas and concepts of geometric optics will be developed through a series of exercises involving OSLO. Concepts on wave optics will be demonstrated through exercises involving either Python or Matlab.
