    Abstract: A color measurement instrument includes a housing and illuminators, a two-dimensional photodetector array, and an optics system within the housing. A UV filter wheel closes the housing to prevent contaminants from entering the housing. The filter wheel supports UV filters and non-UV glass that can be selectively aligned with the illuminators. The photodetectors can be read in parallel, and each photodetector includes a unique spectral filter. The optics system delivers light from the sample target area equally to each of the photodetectors.

    Abstract: Imaging that uses glare to confirm proper measurement of a sample. An imaging device illuminates an object and generates glare (i.e., specular reflection, diffuse reflection or a combination of the two) off the object's surface, which is displayed on a display as a glare artifact. The location of the glare artifact is compared to a predetermined location to establish adjustment to obtain a desired angular orientation. The imaging device optionally highlights the glare artifact and steers a user to obtain the desired presentation angle. In two other embodiments, the spatial relationship between the imaging device and the object is time-varied. In one, the imaging device monitors changing glare and acquires a measurement when a desired glare is detected. In the other, the imaging device captures multiple images including varying glare artifacts and analyzes the images to select a preferred image having a glare artifact indicative of a desired angular orientation.

    Abstract: A method for monitoring a process output with a highly abridged spectrophotometer. The method includes securing spectral data for each spectral primary used in a process, measuring spectral data with a highly abridged spectrophotometer for a sample produced by the process, determining an estimated weight for each spectral primary in the sample, and computing spectral data representative of the sample based on the secured spectral data and the determined estimated weight for each spectral primary in the sample.

    Abstract: Ein Farbmessinstrument hat ein Gehäuse und Beleuchtungsvorrichtungen, eine zweidimensionale Fotodetektormatrix und ein optisches System innerhalb eines Gehäuses. Ein UV-Filterrad schließt das Gehäuse, um ein Eintreten von Schmutzstoffen in das Gehäuse zu verhindern. Das Filterrad stützt UV-Filter und ein Nicht-UV-Glas, die wahlweise mit den Beleuchtungsvorrichtungen ausgerichtet werden können. Die Fotodetektoren können parallel lesen, und jeder Fotodetektor hat einen einzigen Spektralfilter. Das optische System führt das Licht von einem Mustertargetbereich gleichmäßig zu jedem Fotodetektor zu.

    Abstract: 2149401 9412856 PCTABS00032 A color measuring system (10) includes a portable spectrophotometer (100) connectable to a general-purpose computer (130). The portable unit (100) includes a microprocessor with a read-only program memory for storing machine executable instructions and input/output functions. A random-access data memory is used to temporarily store process data for later transfer to the general-purpose computer (130) or to store in a command buffer area transferred high-level, generalized commands from the general-purpose computer (130). The microprocessor also includes a command interpreter which reads a generalized command from data memory and executes the predefined sequence of machine executable functions.

    Abstract: An instrument and related process for measuring color, shade, gloss, shape and/or translucence of a tooth. First, the instrument uses searchlight illumination to illuminate a tooth with constant irradiance. Second, the instrument uses calorimetric imaging to collect time-separated frames of different wavelengths of light reflected from a tooth and to combine those frames into a color image. Third, the instrument includes a sanitary shield to establish a reference color and a predetermined distance to a target tooth. Fourth, the instrument provides line-of-sight viewing so an operator may simultaneously view a display of the image on the instrument and the object being measured. Fifth, the instrument is impervious to pollutants because it incorporates a sealed measurement window. Sixth, optical measurements of a tooth taken by a dentist are compared to optical measurements of a prosthetic restoration for that tooth to confirm satisfactory matching of optical characteristics of the tooth and restoration.
