Abstract: A method of determining a chromaticity rank of a light emitting device includes selecting the light emitting device having a chromaticity rank in a region surrounded by four defining points on a 1931 CIE Chromaticity Diagram. A ratio of a distance in a y-direction between, of the four defining points, two defining points furthest from each other in the y-direction to a distance in an x-direction between, of the four defining points, two defining points furthest from each other in the x-direction is 0.5 or less A peak light emission wavelength of the blue light emitting element is in a range of 447 to 452 nm, a peak light emission wavelength of the green light emitting element is in a range of 520 to 541 nm, and a peak light emission wavelength of the red light emitting element is in a range of 630 to 632 nm.

Abstract: In a direct stimulus value reading type colorimetric photometer, first, second, and third colorimetric optical systems have spectral responsivities approximate to first, second, and third parts of the color matching function, respectively. A deriving unit derives a colorimetric value corresponding to a case in which the color matching function is selected as an evaluation function for colorimetry and a photometric value corresponding to a case in which the spectral luminous efficiency is selected as an evaluation function for photometry (i.e. “CASE”) from three signals. The spectral luminous efficiency is not consistent with any one of the first, second, and third parts. A fourth colorimetric optical system may have spectral responsivity approximate to the spectral luminous efficiency, and the deriving unit may derive the colorimetric value corresponding to the CASE from a fourth signal.

Abstract: The color response of camera devices may be calibrated, using a correction factor that can account for differences in the spectra of light emitted by different light sources used during calibration. The correction factor may be calculated based on the expected spectral sensitivities of the camera devices, the power spectrum of an actual light source, and the power spectrum of a canonical light source. The correction factor is then applied to adjust a measured color response of a given camera device, so that the adjusted color response is effectively the response of the given camera device if it had been illuminated by the canonical light source. In this manner, any measured color response differences, which may be due to differences between the actual light source used and the canonical light source, can be effectively reduced (if not essentially eliminated.) Other embodiments are also described and claimed.

Abstract: A photosensor testing apparatus can be used to test photosensors. A light module can produce simulating light that corresponds to scintillating light of a scintillator or a derivative of the scintillating light. A photosensor under test can produce an output that can be analyzed. A particular photosensor can be determined to have a higher quantum efficiency, a higher signal-to-noise ratio, or another performance criterion and selected for use in a radiation detection apparatus having the scintillator that can produce the scintillating light. The photosensor testing apparatus can provide a more accurate way of selecting a photosensor as compared to only analyzing an emission spectrum and data sheets and other information for the photosensors under consideration.
