AIMS
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.
LECTURE SYLLABUS
Fourier Holograms and Correlation (6L, Dr T.D. Wilkinson)
- 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
holograms.
Electro-Optic Systems (6L, Dr T.D. Wilkinson)
- 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
- Wavelength filters and routing systems
- The BPOMF and 1/f JTC correlators.
Adaptive optical Systems (4L Dr S. Morris)
- Adaptive systems in free space optics;
- Adaptive optical interconnects;
- Optical aberrations and optical correction techniques;
- Optical trapping and tweezing techniques;
Demonstrations in the lectures will include:
- 2D Fourier transform and
diffraction patterns.
- Computer generated hologram
for optical fan-out.
- Optical beam steering with
dynamic holograms on SLMs.
OBJECTIVES
On completion of the module students should:
- Appreciate the derivation
and application of diffraction and Fourier optics;
- Be able to apply Fourier
techniques to simple optical spatial patterns;
- Understand the principles
of optical correlation and holography;
- Understand the principles
of liquid crystal phase modulation;
- Be able to explain the
principles and construction of spatial light modulators (SLMs);
- Know the basic function of adaptive optical systems;
- Understand the properties of optical aberrations and how to correct them;
- Understand the basci principles of optical trapping and tweezing;
