    摘要: Method and apparatus for the determination of total sulfur is described. The method of the present invention for the determination of total sulfur comprising the steps of (1) diluting a sample of a gas in a ozone containing atmosphere to oxidize the sample to form sulfur dioxide from the oxidizable sulfur containing components thereof, (2) subjecting the oxidized sample to infrared radiation at a wavelength selected for the absorption thereof by sulfur dioxide and (3) determining the sulfur content as a function of the infrared absorption. The sulfur dioxide is determined indirectly utilizing methodologies such as nondispersive infrared, or Fourier transformation infrared technology may be utilized in determining the concentration of SO 2 in the sample. The apparatus of the present invention includes a diluter (12) for the dilution of the sample gas with an oxygen containing gas and for the control of the flow rate of the diluted gas being monitored. The diluter communicates with a SO 2 detection unit (24) for the determination and read out of the sulfur content of the monitored gas sample as the result of the absorption of infrared radiation by the sulfur dioxide of the sample gas.

    摘要: Devices image radiation from a scene that includes two materials with spectral characteristics in two different wavelength regions. A lens forms an image of the scene on a detector that includes an array of elements. A filtering arrangement integrated with the detector allows half of' the detector elements to detect radiation in one of the wavelength regions and the other half of the detector elements to detect radiation in the other wavelength region. Each detector element can be constructed from two different sub-elements that are sensitive to radiation in one of the respective wavelength regions. A blackbody source positioned within the devices reduces drift induced by changes to the environment surrounding the devices. The blackbody source projects radiation onto a region of the detector that, does not receive radiation from the scene. Pixel signals produced from the scene radiation are modified based on pixel signals produced from the blackbody.
