We carry out polarization measurements using a coherent white-light continuum as a light source for channeled spectropolarimetry. The white-light continuum, whose spectrum ranges from the UV to the IR region, is generated in Kr gas by a terawatt femtosecond laser system. The complete set of Stokes parameters from 450-700 nm are reconstructed from one spectral measurement. Also, the effectivenes...

This report reviews briefly the characteristics of high spectral resolution satellite infrared remote sensing. The paper also describes the use of EOS-Aqua AIRS measurements to characterize the surface properties important for IR thermal emission. Infrared rapid transmittance model is used for the sensitivity study of surface parameters and the atmospheric parameters from lower troposphere. Six...

The remotely-sensed soil depth in the visible and near-infrared (near-IR) spectral region is investigated by using a numerical radiative transfer model of the coupled atmosphere and soil media. The sensible depth is determined by examining the downward hemispheric transmittance pro® le, hemispherical re ̄ ectance, and bidirectional re ̄ ectance with diVerent solar zenith angles at diVerent wavele...

Fourier transform infrared (FT-IR) spectroscopy and chemometric techniques were used to discriminate five closely related Salmonella enterica serotype Enteritidis phage types, phage type 1 (PT1), PT1b, PT4b, PT6, and PT6a. Intact cells and outer membrane protein (OMP) extracts from bacterial cell membranes were subjected to FT-IR analysis in transmittance mode. Spectra were collected over a wav...

Meanderline wave plates are in common use at radio frequencies as polarization retarders. We present initial results of a gold meanderline structure on a silicon substrate that functions at a wavelength of 10.6 microm in the IR. The measured results show a distinct change in the polarization state of the incident beam after passing through the device, inducing a 74 degrees phase retardance betw...

Infrared (IR) thermal imaging has aroused great interest due to its wide application in medical, scientific, and military fields. Most reported approaches for regulating radiation are aimed realize IR camouflage not applicable enhance imaging. Here, we introduce a simple effective method process porous glass by femtosecond laser scanning, where distributed nanocavities nanowires were produced, ...

Photoinduced IR absorption measurements are reported on WO3. A photoinduced midinfrared small polaron peak centered at 4800 cm−1 (0.59 eV) was observed. The data were analyzed in the framework of the photon-assisted small-polaron hopping theory and briefly compared to previously published infrared absorption measurements in WO3 and photoinduced IR absorption measurements in high Tc cuprates. PA...

Graphene has emerged as a promising material for infrared (IR) photodetectors and plasmonics. In this context, wafer scale epitaxial graphene on SiC is of great interest in a variety of applications in optics and nanoelectronics. Here we present IR reflectance spectroscopy of graphene grown epitaxially on the C-face of 6H-SiC over a broad optical range, from terahertz (THz) to mid-infrared (MIR...

The human eye cannot recognize the shape of an object behind opaque substrate; however, by reading and imaging infrared (IR) rays emitted from such object, its substrate can be ascertained. In this study, double-sided light-emitting display was deposited on transmission characteristics were measured under various conditions, as changes in thickness substrate, distance between intensity viewing ...

Vanadium dioxide (VO2) is widely recognized as a thermochromic material with great potential for application in smart glazing energy-efficient buildings. The monoclinic (M1) VO2 phase undergoes first-order reversible transition from the semiconductor to rutile metallic state. In this study, an M1 porous film was synthesized via polymer-assisted sol-gel route. Processing parameters, such drying ...
