Light scattering by nanoscale objects is a fundamental physical property defined by their scattering cross-section and thus polarizability. Over the past decade, a number of studies have demonstrated single-molecule sensitivity by imaging the interference between scattering from the object of interest and...
This requires rotation at the angle θ given by \(\tan (2\theta )=2{\epsilon }_{xy}/({\epsilon }_{xx}-{\epsilon }_{yy})\) which eliminates shear strain and brings \(\hat{\epsilon }\) to the diagonal form. The difference of the principal strains \(\delta \epsilon=\sqrt{{(...
A CCD-camera based small angle light scattering (SALS) apparatus has been developed to characterize single micrometric particles. The measured scattering vector spans the range 0.02 - 6.8 1/µm. The incident laser light is collimated to a spot of about 50 µm in diameter at the sample ...
2). As shown in the wide-angle XRD pattern of Fig.2d, there was only a very broad peak without any sharp scattering signals, verifying its amorphous state via melt quenching. The amorphous state was further

the finer high melting point NbC phases replacing Ta2C phases is precipitated along grain boundary, and the preferred orientation slender columnar grain containing with a multitude of deformation twins is formed in weld, which can reduce the number and proportion of high angle grain boundary, attribu...
This boundary may possibly be a low-angle grain boundary, appearing as a series of dislocations [71]. Apart from this boundary dividing the top and bottom parts of the sample, no other grain boundaries were found. Porosity from a single crystal that grew in the bottom part of the sample ...
The DEEPscope achieved deep and LFOV imaging in scattering brain tissues by (1) reducing the power required for LFOV imaging using adaptive excitation, (2) improving the excitation efficiency and scanning speed using optimized PSF and beamlets, and (3) performing fast and large-angle optical ...
where t is time, and the angle brackets denote ensemble average. This also means that the g(2)(0) value is related to the probability P(n) of the source emitting n photons to the mode. In the case of coherent light (photon number probability following Poissonian statistics), g(2)(τ...
In other embodiments, detector system 1544 could be part of a separate angle sensing system (not shown), comprised of an additional light beam (not shown) directed towards stage mirror 1534. The separate angle sensing system would measure the absolute or relative angular orientation of stage mirro...
