    Abstract: There is provided a light receiver which corrects measurement of ultraviolet rays on the basis of measurement of visible right and infrared rays. The light receiver is a light receiver (1) including a first light-receiving element (PD1) and a second light-receiving element (PD2), and a UV cutoff filter (11) in which transmittance of light in an ultraviolet region is lower, in which light after passage through the UV cutoff filter (11) enters the first light-receiving element (PD1), and the first light-receiving element (PD1) and the second light-receiving element (PD2) are switchable between a photodiode (PD_uv) having sensitivity to the ultraviolet region and a photodiode (PD_clear) having sensitivity to a visible light region and an infrared region. Unevenness in incident light is calculated from photocurrents in photodiodes (PD_ir+PD_vis) of the first light-receiving element (PD1) and the second light-receiving element (PD2).

    Abstract: Ambient light sensing and proximity sensing is accomplished using pairs of stacked photodiodes. Each pair includes a shallow diode with a shallow junction depth that is more sensitive to light having a shorter wavelength and a deeper diode with a deeper junction depth more sensitive to light with longer wavelengths. Photodiodes receiving light passed through cyan, yellow, and magenta filters and light passed without a color filter are used to generate red, green, and blue information through a subtractive approach. The shallow diodes are used to generate lux values for ambient light and the deeper diodes are used for proximity sensing. One or more of the deep diodes may be used in correction to lux determinations of ambient light.

    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. Low cost and small form factor spectrometers, and methods for manufacturing the same, also are disclosed.
