CODE PHY3110

 
TITLE Physical Optics

 
LEVEL 03 - Years 2, 3, 4 in Modular Undergraduate Course

 
ECTS CREDITS 4

 
DEPARTMENT Physics

 
DESCRIPTION This study-unit builds on concepts introduced in PHY1145 (Electricity, Magnetism, and Optics), introducing the student to physical optics. Topics covered in this unit include:

The particle interpretation of light; Summary of Fourier Analysis; Further Geometric Optics: Ray Transfer Matrix Analysis with examples; Aberration theory; Interference: Spatial and Temporal Coherence; Interferometers; Single and double slit diffraction, Near and far field diffraction theory; Gaussian beam examples; Grating examples; Babinet’s principle and applications; Polarization (linear, circular and elliptical); Laser physics (holography, quantum optics, metrology, medical applications, environmental sensing, etc. depending on available time); Telescopes (refractors, reflectors, catadioptric); Point Spread Functions and response of imaging systems; Adaptive optics; Gravitational lensing: strong, weak and micro, cosmic telescopes, etc.

Study-unit Aims:

This unit aims to provide students with the opportunity to appreciate the nature of light (with an emphasis on its particle nature) and gain a quantitative understanding of its interaction with matter. It is also envisaged that students will acquire a good foundation of the principles of physical optics and become familiar with calculation of ray transfer matrices as well as describing the diffraction outcome for a general aperture set-up. A wide range of applications will be explored via numerous examples, both descriptive and quantitative. The concepts covered in this unit will also provide a solid basis for students opting to further their studies in astrophysics and astronomical instrumentation (amongst others).

Learning Outcomes:

1. Knowledge & Understanding
By the end of the study-unit the student will be able to:

- appreciate the nature of light (with an emphasis on its particle nature) and gain a quantitative understanding of its interaction with matter;
- calculate ray transfer matrices;
- calculate the diffraction outcome for a general aperture set-up;
- describe the nature of light and produce different approaches to describing some of the well-known properties of light;
- understand the interaction of light and matter in a quantitative way;
- describe scatter theory.

2. Skills
By the end of the study-unit the student will be able to:

- apply fourier analysis to optics and understand their wider application; Quantitatively tackle a wide range of problems in physical optics.
