    Abstract: A method and an apparatus for measuring viewing-angle dependent luminance (luminance characteristic) of an LCD panel by condensing radiation from LCD pixels by means of a condensing device which includes a mirror, and by forming a real image of the pixels on an CCD imaging device. Correct luminance characteristic of the LCD panel is calculated by making a correction of the data thus obtained using a predetermined condensing function. The correction removes blurring of data due to condensing effect of the condensing device, thereby preventing degradation of the resolution of the angular luminance measurement apparatus. The condensing device and the CCD imaging device are moved depending on the viewing-angle of the pixels. When the intensity of light entering the condensing device decreased by the move, the correction is performed.

    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 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. Preferably, a two stage spectral separation is utilized, preferably utilizing a diffraction grating and interference filters.

    Abstract: A method and associated apparatus are disclosed for measuring illumination characteristics of a luminaire having unknown characteristics. The method includes steps of providing an array of calibrated photodetectors in known locations in proximity to a mounting location, and then illuminating the array with a luminaire having unknown illumination properties. The resulting data is used to calculate the luminous intensity vs. angle from the luminaire and the luminous flux of the luminaire. Methods of calibrating the measurement with a known luminaire are presented along with methods of determining the angular position of the detectors in the array. Color-sensitive detectors can be used to determine the angular distribution and average value of the luminaire's correlated color temperature.
