Course Goals

The goals of ECE 460 Optical Imaging are to:

1. Develop an understanding of optical diffraction and image formation

2. Develop an understanding of the measurable properties of optical fields, including polarization, spectra, coherence and intensity

3. Develop an understanding of electronic image sensors and intensity sampling

4. Provide hands on exposure to elementary and advanced imaging systems, including Fourier filtering systems, focal planes, and imaging systems.

Instructional Objectives

ECE 460 combines lectures, discussions, analytic exercises (homework and prelabs), and laboratory exercises to provide an integrated analytic and hands-on understanding of imaging systems. The course consists of three segments: (1) field properties, diffraction and imaging, (2) sensors and sampling, and (3) example systems.

1. At the completion of the segment (1), students should be comfortable with the concept of spatial frequency and multidimensional Fourier analysis. They should have an intuitive understanding the action of lenses, gratings, prisms, and other optical components. They should be able to design, assemble, and analyze basic imaging systems. They should be able to analytically calculate and numerically model spatial field distributions given boundary conditions. These abilities will be evaluated through prelab homework and laboratory exercises. (a, b, c, e, k, m)

2. At the completion of segment (2), students should understand the physical processes of generating light and converting light intensities to electronic signals on focal planes. They should have laboratory experience with CCD detectors and imagers. They should understand the origins of aliasing and other sampling artifacts, and they should be aware of physical and digital processes for counteracting sampling limitations. (a, b, c, e, k, l, m)

3. Segment (3) provides students with hands-on experience in image formation, multidimensional imaging, active illumination, and optical design. At the completion of this segment students should have solid basic understanding of the analog to digital interface in imaging systems and confidence in design and analysis of imaging systems. (a, b, c, d, g, i, j, k, m)
