TL;DR: In this article, the location and the reflection coefficient of a scatterer were recovered using high frequency backscattered data without using the far field approximation, although a separate identity was derived when this approximation was introduced.

TL;DR: The similarities between quantum mechanics and paraxial optics were already well-known to the founding fathers of quantum mechanics as mentioned in this paper, and indeed knowledge of the Paraxial Optics partly informed quantum mechanics.

TL;DR: In this paper, the authors give a classical geometric optics description of incoherent solitons, i.e., those launched by a diffuse source, and provide a simple (universal) analytical description for any nonlinear medium.
Abstract: We give a classical geometric optics description of incoherent solitons—those launched by a diffuse source. This method is intuitive, advances predictions such as the existence of solitons of arbitrary cross section, and importantly, it provides a simple (universal) analytical description for the incoherent solitons of any nonlinear medium. Previously, analytical results were known for the ln I nonlinearity only. [S0031-9007(98)05343-5]

TL;DR: Diffraction and holography are fertile areas for application of signal theory and processing, and research aimed at solving problems at the intersection of wave optics and signal processing promises not only to facilitate the development of 3DTV systems, but also to contribute to fundamental advances in optics and sign processing theory.
Abstract: Diffraction and holography are fertile areas for application of signal theory and processing. Recent work on 3DTV displays has posed particularly challenging signal processing problems. Various procedures to compute Rayleigh-Sommerfeld, Fresnel and Fraunhofer diffraction exist in the literature. Diffraction between parallel planes and tilted planes can be efficiently computed. Discretization and quantization of diffraction fields yield interesting theoretical and practical results, and allow efficient schemes compared to commonly used Nyquist sampling. The literature on computer-generated holography provides a good resource for holographic 3DTV related issues. Fast algorithms to compute Fourier, Walsh-Hadamard, fractional Fourier, linear canonical, Fresnel, and wavelet transforms, as well as optimization-based techniques such as best orthogonal basis, matching pursuit, basis pursuit etc., are especially relevant signal processing techniques for wave propagation, diffraction, holography, and related problems. Atomic decompositions, multiresolution techniques, Gabor functions, and Wigner distributions are among the signal processing techniques which have or may be applied to problems in optics. Research aimed at solving such problems at the intersection of wave optics and signal processing promises not only to facilitate the development of 3DTV systems, but also to contribute to fundamental advances in optics and signal processing theory.
