Optics is one of the most successful branches of classical physics. Applications of optics abound throughout our technology, ranging from microscopy through to photonics. This course will cover the basic theory of geometrical and physical optics and discuss applications of these area in modern technology.
The basic physics of geometrical and physical optics will be introduced, emphasizing physical principles. The module will then pursue various applications of key ideas of optics in modern technology, including examples such as fibre optics, holography and semiconductor lithography.
Sources of light - conventional and laser. Basic operation of lasers. Types of lasers.
Detectors of light - photomultipliers and photodiodes.
Reflection of light. Wavefronts and Rays.
Images formed by plane mirrors.
Reflection at curved surfaces. Convex and concave mirrors. Images in concave and convex mirrors. Mirror formulae and sign convention.
Refraction of light. Snell's law. Total internal reflection. Optical waveguiding.
Refraction of light through prisms.
Refraction at curved surfaces. Refraction through thin lenses.
Formation of images by lenses. Combinations of lenses
