__Introduction to Optics__

__Physics 2311__

__Fall-2013__

The study of optics is very old. Indeed, Isaac Newton
published his Optiks in 1704. In spite of this long history, the demands of
modern science and technology have required an even deeper understanding of light
and its interaction with matter and there are many world-class institutes where
the study of modern optics is pursued in earliest. Diverse application in
medicine, astronomy, communications and various branches of physics have
brought both advances in science and benefits to our daily lives. The Hubble
Telescope and innovative optical design applied to land based telescopes have
vastly improved our understanding of the cosmos extending backward in time to
the beginning of the universe. At the other end of the length scale, modern
microscopy has given us insight into the cellular and molecular word. Fiber
optics, only few years ago a curiosity taught in standard courses on Optics,
now forms the backbone of most modern telecommunications networks.

In our study, we will begin by
examining the nature of light, a theme which has been a leading force in the
development of modern day physics and which has led too much of our fundamental
understanding of the workings of nature at the atomic and molecular level. We
will study classical optics as a means of understanding how optical instruments
work. One tool of interest is the use of modern matrix methods for analyzing
paraxial optical systems. Practical applications will include cameras,
telescopes and microscopes, important optical instruments. Since light has the
properties of a wave, we will look at phenomena that depend on the wave nature
of light. This include interference and diffraction, both of which have
important consequences in he design of optical instruments. As time permits, we will have a closer look
at lasers and holography.

__Syllabus__

Chapters
1-4: These chapters give a brief history, talk about wave motion,
electromagnetic theory, photons, light and propagation of light. We will give
these chapters a very brief survey.Sections 4.3, 4.4 and 4.5 cover reflection,
refraction and Fermat’s Principle. These topics form the basis of geometrical
optics.

Chapter
5: We will cover most of the material, which includes lenses, stops, mirrors,
prisms and fiber optics, optical systems.

Chapter
6: Covers thick lenses, ray tracing, aberrations and GRIN systems.

Chapter
7: Section 7.1, deals with the addition of waves of the same frequency.

Chapter
8: Section 8.1 and 8.2 give a short description of polarized light.

Chapter
9: Covers interference phenomena-slits, interferometers and thin films.

Chapter
10: Covers diffraction-Fraunhofer and Fresnel.

Chapter 13: Modern optics (If time permits)
