    Abstract: A chromaticity testing device of a CRT phosphor screen is provided, which enables the on-line automatic testing. A supporting member is provided for supporting a face panel of a color CRT having a phosphor screen therein. A light source emits UV light toward the phosphor screen placed on the member. A movable sensor unit senses visible light emitted from a position of the phosphor screen due to the illuminated UV light and outputs chromaticity signals for the red, green and blue components of the visible light thus sensed. A judgment section receives the chromaticity signals outputted from the sensor unit to determine the chromaticity values corresponding to the chromaticity signals thus received, and compares the chromaticity values thus determined with corresponding preset values to thereby judge whether the chromaticity values are acceptable or not. A control section controls the sensor unit and the judgment section. The sensor unit is located to be contacted with the surface of the face panel on sensing to avoid the effect of external light under the control of the control section.

    Abstract: Polychromatic light is directed at the surface of a live tooth and color data of light reflected therefrom is recorded, multiplied by the stored power distribution of a first standard illuminant and converted to three tristimulus values. Such values are compared with color values of a first group of stored color dental shades, and if a match occurs within a given tolerance, an indication of the nature of the recipe is produced. A second level search may be carried out against a substantially larger group of stored dental shades in the event of a no-match condition resulting from the first search. Excellent lifelike reproduction of the patient's tooth is enhanced by checking for least metamerism by operating upon the measured data with other illumination standards and selecting the best match under all lighting conditions. Additionally, a translucency factor is calculated, and employed to reduce the opacity of the inner opaque layer of the recipe which would otherwise be indicated should the patient's tooth not have a high degree of translucency. The calculation of a fluorescence factor also enhances excellent reproduction of the live tooth, and is employed to indicate the addition of a fluorescent ingredient to the final recipe.

    Abstract: Optical characteristic measuring systems and methods such as for determining the color or other optical characteristics of teeth are disclosed. Perimeter receiver fiber optics are spaced apart from a source fiber optic and receive light from the surface of the object/tooth being measured. Light from the perimeter fiber optics pass to a variety of filters. The system utilizes the perimeter receiver fiber optics to determine information regarding the height and angle of the probe with respect to the object/tooth being measured. Under processor control, the optical characteristics measurement may be made at a predetermined height and angle. Various color spectral photometer arrangements are disclosed. Translucency, fluorescence, gloss and/or surface texture data also may be obtained. Audio feedback may be provided to guide operator use of the system. The probe may have a removable or shielded tip for contamination prevention. A method of producing dental prostheses based on measured data also is disclosed. Measured data also may be stored and/or organized as part of a patient data base.
