Course Objectives:
To learn basic skills in illumination design, especially the use of design software to carry out an individual project and present the results. Students will:

  •  
    		•  Complete a course project: software modeling, theory, public policy, etc.,
  •  
    		•  Understand illumination-based modeling software,
  •  
    		•  Understand the underlying design principles of nonimaging optics: étendue and edge ray, radiance/luminance, intensity, and illuminance/irradiance,
  •  
    		•  Understand the components of an illumination system: source, optics, and target,
  •  
    		•  Know the limits of ray sampling in nonimaging systems,
  •  
    		•  Gain knowledge of a number of applications: lighting, automotive, and displays,
  •  
    		•  Gain knowledge of developing areas: optimization, tolerancing, and rendering,
  •  
    		•  Learn how to present technical papers in both written (i.e., the professor) and oral (i.e., your peers and the professor) formats, and
  •  
    		•  Potentially present and/or publish your work in an optics conference or journal.
