Textbook (Required)
Introduction to Optics (Second Edition)
by Frank L. Pedrotti and Leno S. Pedrotti
Prentice Hall 1996
ISBN 0-13-016973-0

Course Description

The course covers the textbook Chapter 2 Production and Measurement of Light, Chapter 3 Geometrical Optics, Chapter 5 Aberration Theory, Chapter 6 Optical Instrumentation, Chapter 8 Wave Equation, Chapter 10 Interference of Light, Chapter 11 Optical Interferometry, Chapter 15 Production of Polarized Light, Chapter 16 Fraunhofer Diffraction, Chapter 17 Diffraction Grating, Chapter 21 Laser Basics, Chapter 24 Fiber Optics, and Chapter 25 Fourier Optics. These parts have important applications such as for the development of optical instruments for research, commercial, as well defense industries.

Course Objectives

To gain basic knowledge, and understand the main principles, of the modern optics and their applications to specific areas. Students will learn how to find the solutions to specific questions by applying the optical principles and equations. Students will be able to understand the principles of common optical instruments. At the end of the course, students will be able to design a specific optical system for his/her future research work.


1) Students are expected to attend class and participate by asking questions and answering questions raised by the instructors. Class attendance takes 5% extra credit.

2) The homework assignments make up 45% of the total grade.

3) There will be one midterm exam that makes up 20% of the total grade, and one final exam worth 35% of the total grade. Mark your calendar with the exam dates. You are responsible for being there on time. If you have a religious holiday conflict, let me know during the first week of classes. During an exam you must avoid looking at the work of others.

Grading Criteria

The grade distribution will be as follows.
A 88% and higher
B 72-87%
C 55-71%
D 41-54%
F 40% and below

We use the +/- system so in each range (no A+), the low end will be minus and the high end plus.


1) Homework will be assigned once a time each week, and will be turned in one week late brfore it is due.

2) Homework solution will be posted online below and replaced before next homework is due. Please download it and check your answers if you have any question to your answers.
