sensor terms

 compressive sensing
an emerging field of information theory, called "compressive sensing," offered an alternative approach to conventional image acquisition and compression. Developed by researchers at Caltech, Stanford, the University of California, Los Angeles, and Rice, the technology is based on the idea that datasets, such as those that represent images or signals, often contain a significant amount of structure. When this structure is known, it can be used to extrapolate the image or signal when there's only a limited amount of available data.

     digital micromirror technology
    "The orientation of each mirror is random, which is important, say the scientists, because it provides the best possible sampling for the algorithm to reconstruct the image. The random structure is known and fed into the algorithm." (from  http://www.technologyreview.com/read_article.aspx?ch=specialsections&sc=personal&id=17610#)
