As is known from the literature [59 a], illumination of frozen solutions containing trapped electrons in the e,7 absorption band results in a decrease in the concentration of e,7. It is also well known that, for water-alkaline glasses, with such illumination, a transition of an electron from a trap into the conduction... [Pg.24]

Characteristic of many of the experiments described above and other TERS studies reported in the literature are (a) the use of an inverted microscope or illumination that is closely related to such a configuration, (b) the use of thick probe films, and (c) tips covered with metal grains. Each of these points indicates a non-optimal experimental condition for TERS. In fact, a configuration optimal for TERS requires (a) illumination with a strong polarization component parallel to the tip axis, (b) the possibility to use opaque, massive substrates, (c) an easy control of the adsorbate coverage, and (d) sharp, smooth tips with a... [Pg.399]

The feasibility of employing fluorescent tracers and video imaging analysis to quantify dermal exposure to pesticide applicators has been demonstrated under realistic field conditions. Six workers loaded a tracer with the organophosphate pesticide, diazinon, into air blast sprayers, and conducted normal dormant spraying in pear orchards. They were examined prior to and immediately after the application. UV-A illumination produced fluorescence on the skin surface, and the pattern of exposure was digitized with a video imaging system. Quantifiable levels of tracer were detected beneath cotton coveralls on five workers. The distribution of exposure over the body surface varied widely due to differences in protective clothing use, work practices and environmental conditions. This assessment method produced exposure values at variance with those calculated by the traditional patch technique. [Pg.377]

In order to compare the Vis-NIR instrument equipped with a difihise reflectance probe to a standard laboratory color instrument (in this case, an X-Rite SP-68 integrating sphere spectrophotometer), off-line measurements were carried out on pressed plaques at room temperature, All color values were calculated using a standard A illuminant and a 10° observer angle. [Pg.144]

As long as small spherical nanoparticles (dipolar approximation is applicable to obtain optical properties, instead of solving the complex vector wave equations. As a typical example, here we consider a spherical nanoparticle of diameter a illuminated by a plane wave. Upon illumination, polarization is induced in the nanoparticle and is proportional to the incident field (So), the dielectric constant of the surrounding material, and the polarizability of the nanoparticle as follows. [Pg.129]

The diffuse source of Fig. 4-3 (a) illuminates the endface of a step-profile fiber in Fig. 4-4. This source excites all tunneling and refracting rays, as well as bound rays. In order to determine the power entering the tunneling rays, we must first determine the distribution function. [Pg.157]

The partially diffuse source of Fig. 20-6(a) illuminates a single-mode fiber. We showed in Sections 20-7 and 20-12 that the fundamental mode is most efficiently excited by on-axis beams. Thus, it is intuitive that the more diffuse the source, i.e. the larger 0 , the lower the efficiency of the source in exciting the fundamental mode. To demonstrate this behavior quantitatively, we consider a source with a Gaussian intensity... [Pg.437]
