Optical characteristic measuring systems and methods such as for determining the color or other optical characteristics of teeth are disclosed. Perimeter receiver fiber optics preferably are spaced apart from a source fiber optic and receive light from the surface of the object/tooth being measured.
Optical characteristic measuring systems and methods such as for determining the color or other optical characteristics of teeth are disclosed. Perimeter receiver fiber optics preferably 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. Such methods and implements may be desirably utilized for purposes of detecting and preventing counterfeiting or the like. Low cost and small form factor spectrometers, and methods for manufacturing the same, also are disclosed.

The liquid crystal display according to claim 6, wherein a plurality of fluorescent tubes are included in said housing, and said shielding component is disposed between said plurality of fluorescent tubes and shields the directly incoming light from the adjacent fluorescent tube. 8. The liquid crystal display according to claim 6, wherein said fluorescent tube has a curved tube structure, and said shielding component is disposed between adjacent portions of said curved fluorescent tube. 9. A backlight unit comprising: a housing opened at one side, for accommodating a plurality of fluorescent tubes therein, wherein said housing is opened to the side of a liquid crystal display panel, and the inner surface of said housing forms a reflecting surface; and a shielding component disposed in said housing, for shielding the incoming light from directly entering from one fluorescent tube into the other fluorescent tube and vice verse, wherein said shielding component extends to a position closer to said light guide than the position at which said first fluorescent tube and said second fluorescent tube face said light guide. 10. A backlight unit comprising: a light guide placed at the back of a liquid crystal display panel; a fluorescent tube unit comprising a plurality of fluorescent tubes or a curved fluorescent tube placed at one side of the light guide; wherein said fluorescent tube unit reduces interaction by the incoming light among said fluorescent tubes constituting said fluorescent tube unit by a separator for separating said plurality of fluorescent tubes or the curved fluorescent tube, wherein said separator extends to a position closer to said light guide than the position at which said plurality of fluorescent tubes or said curved fluorescent tube face said light guide, so that a rate of maintenance of luminance of the whole fluorescent tube unit may be brought closer to the rate of maintenance of luminance of a single fluorescent tube constituting said fluorescent tube unit. 11.
