    • Multispectral size-averaged incoherent spatial filtering 

      Almeida, S. P.; Case, S. K.; Dallas, W. J. (Optical Society of America, 1979-08)
      A method of 2-D size-averaged incoherent recognition filtering is described. White light input illumination is used to multiplex chromatically a continuum of inputs differing in their spatial Fourier spectral magnifications. ...
    • Volume holograms constructed from computer-generated masks 

      Case, S. K.; Dallas, W. J. (Optical Society of America, 1978-05)
      A new type of hologram that combines computer-generated holograms with volume holograms is described. This hologram allows arbitrary selection of the location and color of a computer-generated image when white light ...
