摘要： A densitometer apparatus (210) is disclosed and is adapted to provide color density measurements of object samples. The densitometer apparatus (210) comprises a source light (578) for projecting light toward an object sample comprising a control strip (588, 620). A reflection optics assembly (576) is adapted to measure light density reflected from the object sample, when the object sample is in the form of a paper control strip. A transmission optics assembly (618) is adapted to measure transmission density of light rays projected through the object sample, when the object sample is in the form of a film control strip. A motor assembly (426) automatically moves the object sample (588,620) through the apparatus (210) adjacent the source light (578). Pattern definition data is prestored in memory of the apparatus (210). When control strips (588, 620) to be analyzed are "read" through the apparatus (210), a pattern recognition process is employed to compare strip color patches with the prestored data, so as to determine whether the control strip "matches" the pattern definition. The pattern definition data is stored so as to define "regions" where dimensional, positional and spectral color patch properties are within predetermined tolerances. An initial step of the pattern recognition process is to scan measured data representative of the control strip and assign regions. Comparisons of the pattern definition region data and measured control strip region data are then performed to determine whether an appropriate "match" has been obtained.

摘要： Reflectance apparatus is disclosed for obtaining measurement of nonspecular reflected light in which controlled light rays are directed along a transmission path from a light source through a plurality of light traps to expose or illuminate a specimen and nonspecular reflected light is passed from the specimen through the light traps along a transmission path to one or more detectors where the nonspecular reflected light is measured, the detector's field of view being larger than the illuminated area of the specimen over a wide range of specimen to source and detector distances.

摘要： A reflectance photometer for quantitatively measuring diffuse light includes a light source located above a sample. The reflectance photometer also includes a first detector mounted at a preselected scattering angle relative to an axis extending perpendicularly from the sample through the light source. A first linear polarizer is mounted between the sample and the light source. The direction of polarization of the first linear polarizer is vertical to a scattering plane defined by the direction of incoming light from the light source and the direction of reflected light detected by the first detector. A second linear polarizer is mounted between the sample and the first detector. The direction of the second polarizer is parallel to the scattering plane. The reflectance photometer can include a second detector mounted at a second, scattering angle. A third linear polarizer is mounted between the sample and the second detector. The direction of polarization of the third linear polarizer can be perpendicular or parallel to the scattering plane. Generally, the three polarizers are close such that the contributors of scattered light as related to surface noise will be minimized for the first detector and maximized for the second detector, respectively. The optimum settings of the polarizer will depend on the settings of the polarizers, the scattering geometry, the sample orientation and the bulk and surface scattering properties of the sample material.

摘要： A device for making accurate, reproducible light reflectance measurements on an optically nonuniform specimen comprises means for holding the specimen in a fixed position. In one embodiment the specimen is illuminated by light sources that are arranged at acute angles relative to the specimen and (360.degree./N.+-.1.degree.) apart in azimuth, where N=the total number of light sources. The light sources are sequentially energized and deenergized to illuminate the specimen. A light detector receives light reflecting from the surface and generates an electrical signal, which is subsequently processed. In another embodiment the light sources are arranged in pairs in which the two light sources in a pair are simultaneously energized and deenergized and the pairs are sequentially energized and deenergized. A method for measuring reflected light is also provided. The device and method are useful for making biochemical assays with reagent test strips by measuring the tone of coloration of the strips after treatment with a target substance being examined.
