Abstract: Methods and apparatus for detecting biological activities in a specimen such as blood are disclosed. The present invention provides a system whereby the intensity of light with a wavelength within the range of about 600 nm to 800 nm introduced into a sample at a first location is measured as it reemerges at a second location. A significant change in the intensity of the reemerging light indicates the presence of biological activity. Preferably, the intensity is also measured at a fourth location, or alternatively, a second light source is disposed at a third location to permit comparative intensity data to be collected. These data are useful in partially identifying the types of microorganisms present in the sample. In preferred embodiments, light emitting diodes are used as the light sources and multiplexed to a plurality of samples. These signals are either detected using photodetectors and demultiplexed, or are collected using fiber-optic light guides and fed to a photomultiplier tube which generates an intensity signal. In either embodiment, the intensity signal is preferably amplified, digitized and stored in a computer.

Abstract: Optical analytical instruments to determine a physical parameter of a fluid, and methods of operation of such instruments, are shown. These employ a source of suitable optical radiation, a detector means, means defining a zone for the fluid, means defining an optical path from the radiation source through the fluid zone to the detector means, and reading and control circuitry. At least two readings of optical energy that has been influenced by the fluid are taken without there having occurred substantial change to the fluid. During one of the readings a filter of known absorbance is included in the optical path so that the respective reading represents a calibration reading. A calibration-value-determining means is constructed first to compare, effectively, the two readings to remove the effect of the fluid from the value of the calibration reading, second, to compare, effectively the residual value of the calibration reading to a known value based on the known absorbance of the filter, and, third, on the basis of the second comparison, to make a calibration adjustment based on values derived while the fluid sample remained unchanged in the fluid zone. Novel software implementations of the determinations are shown. Specific examples of instruments and methods implementing these features shown are a dual lamp, no-moving part in-line spectrophotometer, a no-moving part reflection colorimeter capable of on-line or off-line operation, a scatter or fluorescence detecting implementation and a turbidimeter.

Abstract: A system for detecting optically-sensitive properties of sheet materials during manufacture includes a first group of bundles of optical fibers that convey light to selected transmitting locations adjacent one face of the sheet material. The system further includes a second group of bundles of optical fibers that collect and convey light transmitted through the sheet material to a light detector. The light detector measures the intensity of light received from each of the bundles of the second group to provide measurements of optically-sensitive properties of the sheet material at selected cross-­directional locations.

Abstract: Apparatus (10) and methods for measuring dark and bright reflectances of translucent sheet material (2) are disclosed. The apparatus (10) comprises first optical means for illuminating one side of the sheet material (2) with a source of electromagnetic radiation. A portion of the radiation is transmitted through the sheet material (2) and another portion of the radiation is reflected by the sheet material. The apparatus (10) also comprises optical gating means (30) that is positioned adjacent the other side of the sheet material (2) in a fixed position relative to the first optical means. The optical gating means (30) absorbs substantially all of the transmitted portion of the radiation when switched to a dark state and reflects substantially all of the transmitted portion of the radiation back through the sheet material (2) when switched to a bright state. The apparatus (10) further comprises second optical means for collecting the reflected portion of the radiation and the portion of the trasmitted portion of the radiation reflected by the optical gating means (30) and retransmitted through the sheet material (2) to provide a total reflectance. The total reflectance has a dark reflectance intensity when the optical gating means (30) is in the dark state and a bright reflectance intensity when the optical gating means is in the bright state. The apparatus also comprises sensing means (60), responsive to radiation collected by the second optical means, for providing a dark signal having a magnitude corresponding to the dark reflectance intensity and a bright signal having a magnitude corresponding the the bright reflectance intensity. The dark and bright signals can be incorporated in known formulae to compute values for quality attributes of the sheet material (2) including opacity and color.

Abstract: An optical metrology device is capable of detection of any combination of photoluminescence light (117), specular reflection (143) of broadband light, and scattered light (115) from a line across the width of a sample (101). The metrology device includes a first light source that produces a first illumination line on the sample (101). A scanning system (116) may be used to scan an illumination spot across the sample to form the illumination line. A detector (130) collects the photoluminescence light (117) emitted along the illumination line. Additionally, a broadband illumination source may be used to produce a second illumination line on the sample (101), where the detector (130) collects the broadband illumination reflected along the second illumination line. A signal collecting optic (402) may collect the photoluminescence light (117) and broadband reflected light (143) and focus it into a line, which is received by an optical conduit (412). The output end of the optical conduit (112) has a shape that matches the entrance of the detector (130).
