摘要:
The operator form of the solution for the wave equation is employed to indicate the symmetry properties of the diffracted field under coherent and partially coherent illumination. Such symmetries are of interest in holography, phase conjugation, and for automatic focusing.

摘要:
The tomography problem is investigated when the available projections are restricted to a limited angular domain. It is shown that a previous algorithm proposed for extrapolating the data to the missing cone in Fourier space is unstable in the presence of noise because of the ill-posedness of the problem. A regularized algorithm is proposed, which converges to stable solutions. The efficiency of both algorithms is tested by means of numerical simulations.

摘要:
The characteristics of speckle patterns produced using scattered 10·6 μm CO2laser radiation are described. At this wavelength, heterodyne detection offers significant experimental advantages over direct detection of sensitivity and reduced contrast. As a simple illustration of heterodyne speckle techniques the heterodyne signals received from radiation scattered from a deep random phase screen are confirmed experimentally to follow a Rayleigh distribution.
