This 2014 IAP course focused on computational imager and spectrometer design by exploring non-isomorphic mapping from the object plane to the image plane of an optical architecture. We examined non-traditional sensor design via simulation and delved into some hands-on approaches to hardware design. The course began with a discussion associated with basic principles of ray optics and wave optics and delved into coded aperture imaging and spectrometer design. Participants built their own spectrometer and assessed performance characteristics of coded aperture imagers and light field sensors alike. Finally we reviewed past and present state-of-the-art computational imagers from the literature.
