  • Comparison of field and laboratory collected midwave and longwave infrared emissivity spectra / data reduction techniques

    Abstract Many targets that remote sensing scientists encounter when conducting their research experiments do not lend themselves to laboratory measurement of their surface optical properties. Removal of these targets from the field can change their biotic condition, disturb the surface composition, and change the moisture content of the sample. These parameters, as well as numerous others, ...

  • The importance of background in the Detection and Identification of Gas Plumes using Emissive Infrared Hyperspectral Sensing

    Abstract Using a Fourier transform infrared field spectrometer, spectral infrared radiance measurements were made of several generated gas plumes against both a uniform sky and terrestrial background. Background temperature, spectral complexity, and physical homogeneity each influenced the success of emissive infrared spectral sensing technology in detecting and identifying the presence of a ...

  • INFRARED TECHNOLOGY - It`s Use in Forensic Building Science to Solve Moisture Intrusion Problems

    This paper will focus discussion on the building envelope, the science behind the inspection, techniques for inspection, and verification of the findings. Because much of our work is pioneering, we will end by addressing the question 'Where do we go from here?' WHY USE INFRAREDA picture says a thousand words; infrared thermography is the only diagnostic technology that lets you instantly ...

  • Canopy gas exchange measurements of cotton in an open system

    A portable, open transparent chamber system for measuring canopy gas exchanges was developed and tested. Differentials between incoming and outgoing atmospheric H2O and CO2 concentrations were used to calculate canopy transpiration (E) and net assimilation (A) at 10-s intervals using solenoid valve actuated sample lines connected to an infrared gas analyzer. A programmable data logger controlled ...

  • On Line Measurement of Oxygen: Review and New Developments

    Keywords Oxygen. Paramagnetic, Zirconia, Tunable Diode Lasers Abstract Oxygen is vitally important to the existence of animal life, not only for respiration, but also for the many aspects of the combustion reaction (power generation, vehicular movement, heating) and process control, safety and quality. Continuous measurement techniques are correspondingly ...

  • Measurement of a Doubly Substituted Methane Isotopologue, 13CH3D

    ABSTRACT: Methane is an important energy resource and significant long-lived greenhouse gas. Carbon and hydrogen isotope ratios have been used to better constrain the sources of methane but interpretations based on these two parameters alone can often be inconclusive. The precise measurement of a doubly substituted methane isotopologue, 13CH3D, is expected to add a critical new dimension to ...

  • Real Time Measurments of Acetylene in Ethylene Manufacturing Process

    Keywords Tunable Diode Laser, Wavelength Modulation Spectroscopy, Analyzer, Acetylene, Ethylene, Acetylene Converter Abstract The analyzer, based on near infrared Tunable Diode Laser Absorption Spectroscopy (TDLAS), was developed for the measurement of acetylene in process streams. Measurements of acetylene were made as under laboratory conditions and in ...

  • Deposition temperature effects on optical and structural properties of amorphous silicon carbide films

    Hydrogenated amorphous silicon carbide thin films (a–SiC:H) were elaborated by DC magnetron sputtering technique by using 6H–SiC as target. The a–SiC:H films of 0.9–1.5 µm thicknesses were deposited at different temperatures of 250, 350, 450 and 550°C on p–type Si(100) and Corning glass 9075 substrates. The deposited films (a–SiC:H) were investigated by Infrared Spectroscopy (FTIR), ...

  • Measurement of soil CO2 efflux under experimental warming in Northern Mongolia

    Some of the most extreme temperature increases associated with global climate change are expected to occur in northern Mongolia, and increases in both temperature and the length of the growing season are already apparent (Nandintsetseg and Goulden 2003). The ecology around Lake Hövsgöl in northern Mongolia is of special interest because taiga forest and steppe grasslands come together ...
