TL;DR: In this paper, the suppression and control of multiple light scattering events are investigated because they offer the possibility of optical focusing and imaging through biological tissues, and they may open new avenues for diagnosis and treatment of several human diseases.

TL;DR: In this article, the scattering and reflecting properties of surfaces which are perfectly conducting but which have random irregularities are investigated in a statistical manner, where the surface is assumed to be not too precipitous.
Abstract: The scattering and reflecting properties of surfaces which are perfectly conducting but which have random irregularities are investigated in a statistical manner. The surface is assumed to be not too precipitous. With a statistical model for the surface, the scattering of light by a disturbed water surface is considered, and the method is used to calculate the amount of sea clutter observed in centrimetric radar. A comparison with some observations is made.

TL;DR: In this paper, low-angle x-ray scattering and small-angle light scattering were analyzed using the Tsvankin-Buchanan technique and led to values of the repeat period of the lamellar structure and the thickness of the crystalline and amorphous layers.
Abstract: Solvent-cast films of blends of poly(ϵ-caprolactone) (PCL) with poly(vinyl chloride) (PVC) were examined by low-angle x-ray scattering and by small-angle light scattering. X-ray scattering from crystalline compositions were analyzed using the Tsvankin–Buchanan technique and led to values of the repeat period of the lamellar structure and the thickness of the crystalline and amorphous layers. With increasing content of PVC, the amorphous layer thickness increased sufficiently to accommodate the PVC, leading to values of the linear crystallinity consistent with macroscopic measurements by density and DSC techniques up to about 50% PVC by weight. Above this concentration, the lamellar structure no longer appeared to be volume filling. At high concentration of PCL, the polymer consisted of volume-filling spherulites containing the lamellar substructure. Spherulite sizes were measured by light scattering and absolute light scattering intensities were consistent with calculations based upon the degree of crystallinity and anisotropy of the spherulites. Compositions containing more than 60% PVC were amorphous. Low-angle x-ray scattering was interpreted in terms of the Debye–Bueche theory which leads to values for a correlation distance lc and the mean-square electron density fluctuation 〈η2〉 (which was also obtained from the invariant). By the method of Porod, the correlation distances were resolved into persistence lengths within the two phases, which were determined as a function of composition. The fluctuation 〈η2〉 was analyzed in terms of a two-phase model to show that its value was somewhat larger than would be obtained if the phases were composed of the pure components. It was not possible to uniquely determine their compositions. The data were consistent with the existence of a transition zone of the order of 30 A thick between phases.

TL;DR: In this article, a method for calibrating photodetectors based on some characteristics of the statistics of the field of spontaneous parametric light scattering is described, and a phenomenological theory of parametric scattering is used to demonstrate that photons are only emitted in pairs.
Abstract: A description is given of a method for calibrating photodetectors based on some characteristics of the statistics of the field of spontaneous parametric light scattering. A phenomenological theory of parametric scattering is used to demonstrate that photons are only emitted in pairs. It is shown that, in principle, a priori information on the two-photon character and directionality of parametrically scattered light can be used for absolute calibration of photodetectors operated both in the analog linear regime and in the discrete photoelectron pulse counting regime.
