    Abstract: An apparatus and non-invasive method of measuring oxygen by exciting a luminescent compound disposed in a container and then measuring the intensity of the light emitted by the excited luminescent compound as it relaxes to the ground state. A plot of emission intensity as a function of time results in an exponential decay curve the area of which is inversely proportional to the oxygen concentration. The oxygen concentration can be determined over a wide temperature range by measuring the temperature of the container and the emission intensity and then applying the following equation: [O2]=(ATa(T)2+BTa(T)+CTa)(tau)2+(ATb(T)2+BTb(T)+CTb)(tau)+(ATc(T)2+BTc(T)+CTc) T is the measured temperature; tau is the area of the exponential decay curve; and ATa, BTa, CTa, ATb, BTb, CTb, ATc, BTc, and CTc are coefficients that are specific to the luminescent compound being examined.

    Abstract: An apparatus and method for detecting at least one component gas in a sample includes a radiation source for providing radiation along an optical path in a pre-selected spectral band having at least one absorption line of the component gas to be detected and an optical detector for detecting radiation at the optical path. A sample chamber is positioned in the optical path between the source and the optical detector to contain a quantity of a sample gas. At least one gas cell enclosing an amount of the gas to be detected is fixedly positioned in the optical path in series with the gas chamber. A mathematical relationship is determined between the detected radiation and the concentration of a sample gas filling the sample chamber.

    Abstract: Optical systems are provided. One such optical system includes an optical source that propagates a source beam of light. A diffracting component is optically coupled to the optical source and is operative to receive the source beam and produce a diffracted beam. A target is located to receive the diffracted beam. Additionally, a compensating system repositions at least one of the optical source, the diffracting component, and the target in response to a detected change in refractive index of a medium through which the diffracted beam propagates so that the diffracted beam continues to be received by the target. Methods and other systems also are provided.

    Abstract: Apparatus and methods for use in measuring the moisture content of heavy-grade sheets of paper during their continuous manufacture. In one aspect, means employing infrared absorption techniques for determining the fiber weight per unit area of a sheet having a fiber weight of up to 1100 grams per square meter are provided. In another aspect, means employing infrared absorption techniques including the use of two moisture absorption bands and associated moisture reference bands for calculating the average temperature of the sheet are provided. The latter aspect may be used to produce an indication of moisture weight per unit area, wherein the indication is substantially independent on changes in the average temperature, and enables accurate measurement of the moisture weight per unit area of heavy grades of paper having moisture weights of up to 450 grams per square meter. The former aspect may be employed in measuring the moisture content of heavy grade of paper having moisture weights of up to 90 grams per square meter.
