Abstract: The measuring apparatus of the present invention measures the optical properties of a sample containing a fluorescent material by irradiating the sample with light containing a UV component. In the present invention are provided a first light source for irradiating the sample with light containing a UV component, a second light source for irradiating the sample with light which does not contain a UV component, light receiving element for receiving light reflected from the sample irradiated by said light sources, and output means for generating weighting coefficients for weighting the output of the light receiving element during emission by each light source. The optical properties of the sample is calculated based on the output of the light receiving element for a first light source, output of the light receiving element for a second light source, and the respective weighting coefficients. Accordingly, measurement values can be obtained which are equal to values when measurement is accomplished with a standard light source.

Abstract: A sample holding apparatus (20) and method for use with an optical analyzing assembly (10) for irradiating a sample (33) with light energy. The sample holder apparatus (20) comprises a sample container (30) having a downwardly facing container opening (44), and a partition (32) movably positioned over the opening (44). A container support (24) is positioned adjacent the partition (32) and includes a surface (26) having an analyzing window (28) for transmitting the light energy therethrough. The container (30) is movably mounted to a transport mechanism (36) which permits the partition (32) to slidably retract from a closed position, across the opening (44), to an open position as the container (30) is urged onto the support surface (26). Consequently, the sample (33) contained in the container (30) is exposed and drawn into direct contact with the analyzing window (28). The wall members (38) of the container (30) retain the particulates of the sample (33) in substantially a same position during the relative movement.

Abstract: An integrating sphere for detecting particles in an aerosol has a diffuse reflectant interior surface and a plurality of photodetectors. The aerosol passing through aligned ducts which are spaced at the center of the integrating sphere, and a beam of collimated light, such as a laser beam, projects transversely through the aerosol in the space. Particles in the aerosol scatter the light, and the scattered light is detected simultaneously by the photodetectors within the integrating sphere. A coincidence detection circuit is used to detect the number of times scattered light is simultaneously detected by the photodetectors and, thereby, count the number of particles in the aerosol.

Abstract: The optical reflectance or transmittance concentration analyzer includes an acousto-optical tunable filter (AOTF). The AOTF is tuned by a computer controlled digital-to-analog converter through a tunable sweep oscillator. Tuned beams can be selected according to their direction of propagation or according to their polarization behavior. Therefore, if desired, a pair of crossed polarizers can be used to select one of the tuned monochomatic light beams that pass from a light source through the AOTF. To obtain rapid wavelength change along with electronic chopping or wavelength modulation, the digital-to-analog converter output is combined with the output of a high speed signal generator. The modulated light is conducted directly or through a fiber optic cable to the location of the optical measurement and impinges upon the sample where it is reflected or transmitted. The emerging light is collected onto detector(s). The measurement time interval can be distributed among the required wavelengths or wavelength pairs according to an unequal scheme to decrease the error of the result in a calibration equation. The apparatus is particularly adaptable for use as an on-line concentration monitor in industrial process control because of its stability, efficiency and ability to perform quick analyses.

Abstract: A method for optically measuring at least one characteristic of a thin film on a reflecting substrate. A p-polarized beam of collimated light of known intensity is directed through an integrating sphere onto the film at substantially the Brewster's angle of the film. All the light is reflected into the sphere, including all diffusely reflected light as well as the light specularly reflected at a region inside the sphere where the specularly reflected light is incident. A reflective surface is provided for determining the thickness of the film as a function of the total intensity of light sensed within the sphere. An absorptive surface is provided at said region for absorbing the specularly reflected light for determining the porosity or surface roughness of the film based on the intensity of the diffused light sensed within the sphere not reflected from the substrate.

Abstract: Monochromatic infrared radiation of variable wavelengths between 1.0 and 3.5 microns is directed upon a portion of a moving web, and the spectra of infrared radiation reflected from the web portion and of radiation transmitted through the web portion are separately measured by sensors located on both sides of the web. These spectra are combined to provide an absorption spectrum insensitive to any elastic scattering that is also present. Measures of the contents of the web constituents are generated by least-square fitting the individual absorption spectra of the constituents to the measured absorption spectrum of the web. Means for calibrating the reflectance and transmittance measurements and for keeping the sensor viewing windows free of dirt and dust are also disclosed.
