Abstract:
Fiber optics were used to interface a Raman spectrometer to a long (1 m) sample tube, with the objective being increased sensitivity. Internal reflection of the laser light and the Raman scatter within the sample tube permitted a long solution length to be sampled, increasing the Raman sensitivity by factors of 30–50 over conventional capillary tube sampling systems. In addition, the sample was subjected to much lower power densities than with systems employing a focused beam, thus minimizing radiation damage. Detection limits of 10−9 to 10−8 M were achieved for resonance Raman scatterers, and

Abstract:
AbstractA long-path methane (CH4) sensor was developed and field deployed using an 8-μm quantum cascade laser. The high optical power (40 mW) of the laser allowed for path-integrated measurements of ambient CH4 at total pathlengths from 100 to 1200 m with the use of a retroreflector. Wavelength modulation spectroscopy was used to make high-precision measurements of atmospheric pressure–broadened CH4 absorption over these long distances. An in-line reference cell with higher harmonic detection provided metrics of system stability in rapidly changing and harsh environments. The system consumed l

Abstract:
A Liquid-Core Waveguide (LCW) detection system for high sensitive determination of tegaful (FT) was developed. In this system the LCW cell was connected to the end of a hollow cathode lump and the other end to a UV spectrometer. A sample solution containing FT was pumped to the LCW cell through a T-shaped connector. A UV absorption of analyte was detected by the UV spectrometer. The configuration of connectors of LCW cell to the light source and the UV detector was designed. Stable and high responses of FT were obtained in a double tube system in which an edge of LCW cell was covered with anot

Abstract:
The optical properties of a novel fused silica fiber-optic capillary waveguide (FOCap) for fluorescence spectroscopy were evaluated. Evanescent fluorescence from samples in the FOCap was measured by coupling the FOCap to a light source and a fluorescence spectrophotometer. The FOCap has negligible excitation light loss over long lengths (20 m or more) for a range of wavelengths. The evanescent fluorescence was linear up to at least 20 m for a solution in the core and up to at least 15 m for a fluorophore covalently attached to the inner surface.

Abstract:
Generally, turbulence in the atmosphere has been described by a Kolmogorov-Taylor (K-T) model. In some cases deviations from this simple theoretical model have been found. Measurements of phase fluctuations in light paths through the atmosphere presented here indicate that under typical astronomical observing conditions these deviations can be significant. This result is particularly important for prediction of the performance of large filled-aperture telescopes or long-baseline interferometers at infrared wavelengths. Analysis of the statistics of these pathlength fluctuations shows that they

Abstract:
Careful measurements of pressure broadening in CO2 have been made in the v3 band of CO2. The sample was contained in a 2m long multiple traversal cell set for four transits. The long pathlength allowed very low partial pressures of CO2 to be used. The temperature could be set anywhere between room temperature and 200 K and several recordings were made in this range. Nitrogen, oxygen and air (actually mixtures of pure nitrogen and oxygen since laboratory air contained far too much CO2) were used as collision partners at pressures up to 200 Torr.

Abstract:
Rocket engine exhaust plume is generally thermal in character arising from changes in the internal energy of constituent molecules. Radiation from the plume is attenuated in its passage through the atmosphere. In the visible and the infrared region of the spectrum for clear-sky conditions, this is caused mainly through absorption by atmospheric molecular species. The most important combustion-product molecules giving rise to emission in the IR are water vapor, carbon dioxide, and carbon monoxide. In addition, the high temperature plume reacting with the surrounding atmosphere may produce nitro
