Terahertz transmission spectroscopy of chalcogenide glasses

2008 33rd International Conference on Infrared, Millimeter and Terahertz Waves, 2008
Terahertz transmission of a chalcogenide family of glasses is reported. The glasses were processed using established methods for non-oxide glasses. Transmission through the samples was measured using a THz spectrometer. The transmission and optical properties of the glasses are summarized.

Transmission spectroscopy of dengue viral infection

Laser Physics Letters, 2012
We presented the rapid diagnostic test for dengue infection based on light spectrum of human blood. The transmission spectra of dengue infected whole blood samples have been recorded in ultra violet to near infrared range (400 – 800 nm) of about 30 conformed infected patients and compared to normal blood samples. Transmission spectra of dengue infected

A standard for transmission electron spectroscopy

Proceedings, annual meeting, Electron Microscopy Society of America, 1978
A variety of standard specimens is needed in order to systematically investigate the instrumentation, specimen, data reduction and quantitation variables in electron energy-loss spectroscopy (EELS). Pure single element specimens (e.g. various forms of carbon) have received considerable attention to date but certain elements of interest cannot be ...

Terahertz homodyne self-mixing transmission spectroscopy

Applied Physics Letters, 2015
A compact homodyne self-mixing terahertz spectroscopy concept is experimentally investigated and confirmed by calculations. This method provides amplitude and phase information of the terahertz radiation emitted by a photoconductive antenna in a transmission experiment where a rotating chopper wheel serves as a feedback mirror.

Photoluminescence and infrared transmission spectroscopies of

Semiconductor Science and Technology, 1997
The first detailed photoluminescence (PL) study of as-grown samples obtained from three different sources is presented. The study was carried out in the 5 - 100 K temperature range and laser excitation densities 0.5 - 5 . PL spectra collected on samples from all sources showed a PL band near 355 meV which is assigned to an transition to the deep native

Absorber transmissivities in57Fe Mössbauer spectroscopy

Hyperfine Interactions, 1985
Some useful relations are derived for the polarization dependent optical index of57Fe Mossbauer absorbers. Real rotation matrices are extensively used and, besides wave-direction dependence, their properties simplify also the treatment of texture andf-anisotropy.

Temporal and Spatial Resolution in Transmission Raman Spectroscopy

Applied Spectroscopy, 2010
Picosecond time-resolved transmission Raman data were acquired for 1 mm thick powder samples of trans-stilbene, and a Monte Carlo model was developed that can successfully model the laser and Raman pulse profiles. Photon migration broadened the incident (∼1 ps) probe pulse by two orders of magnitude.

Rapid quantitative protein detection by light transmission spectroscopy

Applied Optics, 2019
Rapid, sensitive, and quantitative protein detection is critical for many applications in medicine, environmental monitoring, and the food industry. Advancements in detection of proteins include the use of antigen-antibody binding; however, many current methods are time-consuming and have limiting factors such as low sensitivity and the inability to ...

Biological Sensing Using Transmission Surface Plasmon Resonance Spectroscopy

Langmuir, 2004
Ultrathin gold island films evaporated on transparent substrates offer promising transducers for chemical and biological sensing in the transmission surface plasmon resonance (T-SPR) mode. In the present work, the applicability of T-SPR-based systems to biosensing is demonstrated, using a well-established biological model system.

Ultrasound transmission spectroscopy: In-line sizing of nanoparticles

2014 IEEE International Ultrasonics Symposium, 2014
Nanoparticles are increasingly used in a number of applications, e.g. coatings or paints. To optimize nanoparticle production in-line quantitative measurements of their size distribution and concentration are needed. Ultrasound-based methods are especially suited for in-line particle sizing.
