  • Fresnel Holograms: Their Imaging Properties and Aberrations

    Publication Year: 1965, Page(s):171 - 178
    Cited by:  Papers (4)

    A simple and unified treatment is given of the properties of the magnified or demagnified images reconstructed from Fresnel holograms. The resolution attainable in wavefront reconstruction is discussed with particular attention to the aberrations of reconstructed images. Explicit expressions are given for the five primary wave aberrations, viz., spherical aberration, coma, astigmatism, curvature o... View full abstract»

  • Analysis of the Impurity Atom Distribution Near the Diffusion Mask for a Planar p-n Junction

    Publication Year: 1965, Page(s):179 - 186
    Cited by:  Papers (47)

    Presented here are the results from a mathematical investigation of the impurity atom distribution within a planar p-n junction. Two fundamentally different diffusion processes are considered: In the first, a constant impurity atom concentration is maintained at the semiconductor surface; in the second, a fixed quantity of impurity atoms is involved in the entire diffusion process. The results of ... View full abstract»

  • Some Numerical Experiments in the Theory of Polynomial Interpolation

    Publication Year: 1965, Page(s):187 - 191
    Cited by:  Papers (2)

    An important unsolved problem in the theory of polynomial interpolation is that of finding a set of nodes which is optimal in the sense that it leads to minimal Lebesgue constants. In this paper results connected to this problem are obtained, and some conjectures are presented based upon numerical evidence garnered from extensive computations. View full abstract»

  • Chain Matrices and the Crank-Nicolson Equation

    Publication Year: 1965, Page(s):196 - 199

    In Reference 1, a practical application of the special properties of a class of matrices called chain matrices is made to obtain numerical solutions of partial differential equations of the elliptic type. In this communication, we wish to present an application of these matrices to the study of the problem of obtaining numerical solutions of parabolic partial differential equations. This method is...

  • A Drive Scheme for the GaAs-Si Light-Activated Switch

    Publication Year: 1965, Page(s):200 - 202
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (293 KB)

    The development of a GaAs-Si light-activated switch, designed to serve as a building block in an integrated electronic gating system (multiplexor), has been reported1–3 It was found that the usefulness of the gating system could be greatly amplified if a simple drive scheme could be designed to operate compatibly with it. Such a drive scheme has been developed, and is briefly des... View full abstract»

  • A New Technique for Dynamic Analysis of Acoustical Noise

    Publication Year: 1965, Page(s):205 - 208
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (392 KB)

    This communication discusses some preliminary work on a new acoustical analysis technique and its application to the detection of noise sources in paper document handling machines. The technique, a time-domain dynamic-analysis method, used in conjunction with the conventional analysis techniques based on frequency and spatial analysis, has permitted the development of design principles for minimiz...
