Abstract: A method and apparatus are disclosed for an analyzer which measures concentration of a liquid specimen by monitoring the coloration of test paper which is either dipped into the specimen or is otherwise painted with it. In the method, inner stray rays produced by a light source which do not reach the test paper are experimentally monitored, so that the effect of such inner stray rays upon the accuracy of the test paper analysis is eliminated. Additionally, a method of relating relative reflectivity of the test paper to the concentration of the specimen is disclosed, in which method the calibration curve is modeled as a section of a hyperbola. In the apparatus, a microcomputer performs the evaluation and the detection of the coloration of the test paper and the compensation for various sources of instrumental error takes place electronically.

Abstract: A method for moisture testing of a fully assembled photovoltaic (PV) module. An assembled PV module is probed with short wave IR probe energy in the range of 1700-2000 nm. Energy reflected from the assembled PV module is collected and directed to a sensor. Noise is removed from a signal of the sensor with reference to the probe energy. Absorption is of the probe energy is determined. The absorption is correlated to moisture in the PV module. A preferred system that carries out the method provides a signal-to-noise ratio (as defined by standard deviation/mean of measured reflectance) of at least 3800.

Abstract: Disclosed is a high reflectivity integrating cavity and device to amplify and detect luminescent emissions produced by small concentrations of materials to be analyzed. Femto or nano molar concentrations of a material can be placed within the high reflectivity integrating cavity. At least the interior surface of the high reflectivity integrating cavity can comprise a coating that, at a designated wavelength of electromagnetic radiation, is transparent and non-absorbing to such designated wavelengths of electromagnetic radiation. In addition to the isotropic field induced by the interior surface of the high reflectivity integrating cavity, the high reflectivity of the interior surface of the high reflectivity integrating cavity leads to very large effective optical path lengths within the interior of the high reflectivity integrating cavity, thereby amplifying the luminescent emissions produced by the sample.

Abstract: The invention relates to a light integrating cavity device, such as an integrating sphere, for measuring diffuse reflectance of a sample. A light trap is movable within a light scattering cavity of the device for controlling specular reflections during measurements. The light trap may be rotatable around the sample under test inside the cavity so that specular reflections off the sample can be included or excluded from the measurement. The sample may also be placed at the outside against a measurement port, and a measurement instrument is moveable on a rotating arm within or outside of the cavity.
