Title: OPTICAL SYSTEM DESIGN
Catalog Description: Ray optics, wave optics in isotropic and anisotropic media, optical instruments, aberrations, fiber optics, optical sources (passive and active), optical elements, and optical detectors. Analysis of multi-component optical systems using linear system techniques. Design and optimization of individual components and multi component systems using Code-V software.
Coordinator: Heba Yüksel, Assistant Professor of Electrical & Electroncis Engineering
Goals: The purpose of this course is to teach optical analysis and design techniques by reference to the performance of many different optical components and systems. Attention will be given to real world design in terms of component selection, optimization, and integration into system.
At the end of this course, students will be able to:
1. Apply design techniques to simple optical systems, explain these design techniques, and demonstrate practical knowledge of issues involved in overall system design.
2. Analyze multi-component optical systems using linear system techniques.
3. Design and optimize individual components and multi component systems using Code-V software.
4. Present rationales for component selection, layout, and system analysis in their design.
5. Present awareness of safety issues related to laser radiation.

Computer Resources: Students will be using Code-V Optical Design Software throughout the course within their project assignments. This software will be made available on selected computers in the Computer Lab of the Electrical & Electronics Engineering Department. Most projects will require computer analysis and graphical results presentation. I encourage the use of softwares such as Mathcad, Mathematica, or Matlab for this purpose.
Laboratory Resources: Computer lab.
Course Structure: The class meets for two lectures a week, one consisting of two 50-minute sessions and the other, just one 50-minute session.
Grading: There will be one mid-term exam and a final exam. All exams will be CLOSED BOOKS CLOSED NOTES. Calculators will only be allowed for scalar algebraic and trignometric computations. There will be individual project assignments which will test your ability to use various design and anlysis techniques that will be covered in the class.

• An ability to design an optical system and perform component design analysis to meet the desired needs: Design techniques of simple optical systems will be covered in class and students will be able to explain these techniques, and demonstrate practical knowledge of issues involved in overall system design.
• An ability to identify, formulate and solve engineering problems: Students are given specific engineering problems such as cameras, telescopes, range finders, optical communication systems, wide-angle lenses, LIDAR, Resonators, Rifle Scope communication systems, 3-D object projector and asked to design and optimize such systems in Code V.
• Use of modern engineering tools. Students will use Code V in project assignments which will test their ability to use various design and analysis techniques that will be covered in class. These projects will include component design analysis and complete system characterization and optimization using Code V.
