... Thermal physical (thermal diffusivity and conductivity) and optical (attenuation, absorption and scattering) properties of alumina fiber insulation materials were measured. The measurements of apparent thermophysical properties are based on the method of heating of plate specimens at a constant...

... The “scattering characterization” that was developed in Marseilles enables us today, with the help of complementary tools (causal model, isotropy degree, …), to point out the origin of micro-roughness in optical coatings without any ambiguity. Each material can be associated to a key parameter...

... Laser light scattering from thin film coatings was evaluated as a diagnostic indicator for an automated 1-on-l laser damage test facility. While variations in scattered light has been effectively used in bulk damage testing for many years, a dependable diagnostic of similar ilk for threshold...

... Reducing losses in optical coatings implies a search for optimal realization conditions of multidielectric coatings to obtain minimal absorption and scattering. Numerous works have been devoted to the absorption problem. Here we deal with scattering minimization. Scattering from a coated...

... by various papers that the nil-ductility transition temperature (NDTT) obtained by this test depends on such parameters as the welding conditions of the crack-starter bead, notch location, and other factors. In this paper, the authors have investigated the scattering of NDTT and discuss the necessity...

... assist, CW laser in UHV, and an advanced epitaxial technique. Characterization included total integrated scatter, spectrophotometry, x-ray diffractometry and pulsed laser damage testing at 532 nm. Our results indicate that considerable additional work will be required to optimize the optical performance...

... is done below the recrvstallization temperature of about 800°C for CaF 2 . Nomarski micrographs show that voids are distributed within the bulk of the forgings. Polariscope photographs show internal stress. Total integrated forward scattering measurements have been made on the sample immersed in a cell...

... obtained by Sparks using a perturbation approach. The results are extended to metal substrates by introducing the concept of a generalized substrate index. An approximate expression for scattering losses for high reflectance coatings is included. Multiple quarter-wave antireflectance coatings are also...

... A review is presented of neutron gaging concepts and applications. The gaging systems are restricted to those that measure elastic or inelastic scattered source neutrons, in either a transmission or scattering geometry. Neutron gaging, in this sense, is not selective. It cannot identify...

... The paper deals with the scatter under program and random loading. For the explanation of the results, constant amplitude tests and tests with biharmonic loading are also included in the study. The basis of the comparison of the data is the logarithmic normal distribution and its parameters...
