Content
The aim of this module is to examine the advance of optical techniques into electronic systems for computation and communications. Two dimensional and three dimensional transmission, storage and processing of information using free space optics are discussed. Applications such as computer generated holography, optical correlation, optical switching and adaptive optics are highlighted through the use of liquid crystal technology.

- Fourier Transforms and Holography introduction and motivation;
- Fourier transforms: theoretical and with lenses: resolution of optical systems;
- Correlation and convolution of 2-dimensional signal patterns;
- Dynamic and fixed phase computer generated holograms.
Electro-Optic Systems (5L)
- Free space optical components; wave plates and Jones matrices
- Fundamentals of liquid crystal phase modulation
- Spatial light modulation and optical systems;
- Holographic interconnects and fibre to fibre switching
