It must be emphasized that the agreement around the maximum in the resistivity for Au-Sn, and in­ deed for all noble metal-Sn alloys is purely quali­ tative. The resistivity integrand in Eq. (7) for high noble metal concentrations is dominated almost en­ tirely by the low angle behaviour of the Iij(K) (see Fig. 5), particularly those for Au-Au and Au-Sn for example, and accurate data in this re...

In functional neuroimaging, a crucial problem is to localize active sources within the brain non-invasively, from the knowledge of the electromagnetic measurements outside the head. Identi cation of point sources from boundary measurements is an ill-posed inverse problem. In the case of electroencephalography (EEG), measurements are only available at electrode positions, the number of sources i...

The earth-atmosphere stray light can lower contrast ratio and SNR of spatial optical remote sensors, or even fail the system at certain conditions. Errors in the calculation of the stray light illuminance based on point source are very large, for the satellite’s altitude is only several hundred kilometers and far less than the radius of the earth. This paper proposed a stray light illuminance c...

The angular resolution of the proposed Square Kilometre Array, SKA, must be extended towards the milliarcsecond scale if it is to resolve the distant starburst galaxies that are likely to dominate the radio source counts at micro and sub-microJy flux levels. This paper considers the best way of extending SKA's angular resolution towards the milliarcsecond scale. Two possible SKA-VLBI configurat...

The reconstruction of sagittal trans-rectal optical tomography for prostate imaging is presented with assumption of structural guidance from trans-rectal ultrasound. The spatial prior combined with Jacobian weighing improves the recovery of lesion depth. © 2008 Optical Society of America OCIS codes: (170.6960) Tomography; (170.3010) Image reconstruction techniques; (170.7230) Urology

We extend the phase modulation method by in-plane diffractions from plane wave incidence to point source of surface plasmon polariton (SPP). A well-defined SPP focus is successfully realized from a point source under the diffraction by a carefully designed nanohole array, which is easy to layout in the future integrated optical circuits. With this method, the SPP Airy beam and finite plane wave...

Reconstructions of a three-dimensional absorber embedded in a scattering medium by use of frequency domain measurements of the transmitted light in a single source-detector plane are presented. The reconstruction algorithm uses Bayesian regularization and iterative coordinate descent optimization, and it incorporates estimation of the detector noise level, the source-detector coupling coefficie...

We study the inverse fluorescent source problem for optical molecular imaging. In particular, we recover key properties of a fluorescent source inside a halfspace composed of a uniform absorbing and scattering medium from angularly resolved measurements at the boundary plane. We use the radiative transport equation to model the multiple scattering of light in tissues. Using Green’s function, gi...
