EECE 571R (Electrical Engineering Seminar and Special Problems – MODERN OPTICS)

Overview

Optics (or Photonics) has been revolutionizing many areas in our lives. However, to many non-Optics professionals, they may not be aware of how Optics is impacting our lives. In this course, we will explore four Optical techniques and see how they contribute to material characterization, image processing, data storage, and communication. Students in this course will gain working knowledge and learn principles behind the techniques. Hopefully by the end of the course, the students will be aroused to learn more Optics and start applying Optics to solve technical problems.

Learning Objectives

The course is expected to appeal to students in Electrical and Computer Engineering, Mechanical Engineering, Biomedical Engineering, Engineering Physics and Physics.  On the successful completion of this course, the students will be able to:

  • Achieve a sufficient understanding of the principles of the optical techniques and their limitations
  • comprehend research literature that utilizes techniques covered in this course
  • generate CGH for a given image
  • perform numerical reconstruction of digital hologram

For students involved in Photonics research, in addition to the above, they will be able to:                 

  • setup a PPR system for measuring the thermal properties of thin films or nanostructures           
  • setup coherent optical signal processor for filtering optical information
  • setup optical system for acquiring digital hologram
  • fabricate CGH and phase plate
