    • Two-stage spatial-filtering for diffraction pattern-analysis 

      Blodgett, Jerry; Easton, Roger (Optical Society of America, 1981-03)
      The use of optical power spectrum analysis for feature detection and classification is often restricted by the superposition of the aperture spectrum. A spatial frequency filtering technique using a circular aperture and ...
    • Using neural networks for controlling chaos 

      Alsing, Paul; Gavrielides, Athanasios; Kovanis, Vassilios (The International Society for Optical Engineering (SPIE), 1994-03)
      A feed-forward backpropagating neural network is trained to achieve and maintain control of the unstable periodic orbits embedded in a chaotic attractor. The controlling algorithms used for training the network are based ...
