ECE 498 LG

Subject offerings of new and developing areas of knowledge in electrical and computer engineering intended to augment the existing curriculum. See Class Schedule or departmental course information for topics and prerequisites. Course Information: 0 to 4 undergraduate hours. 0 to 4 graduate hours. May be repeated in the same or separate terms if topics vary.

Prerequisite: ECE 350 This course is a comprehensive introduction to the optical design of lenses and imaging systems. This course begins with a review of basic optics, including geometrical optics and Fourier optics. A discussion of how different system specifications influence the choice of design form, achievable performance, and cost will be presented. Aberration theory, stop shift theory, and induced aberrations are examined in detail. Factors that affect aberrations and the principles of aberration correction are discussed. Demonstrations of computer aided lens design are given accompanied by a discussion of optimization theory, variables and constraints, and local vs. global optimization. Techniques for improving an optical design are illustrated with easy-to-understand Zemax examples.
