Abstract: The present invention relates to a fluorescent image system capable of generating white light by mixing three monochromatic lights, i.e. red, green and blue monochromatic lights, having a narrow band wavelength, instead of white light of constant wavelength; providing a fluorescent image-use light source that generates a mixed light by adding a fluorescent excitation light source suitable for fluorescent substances; and photographing a general image and fluorescent image simultaneously with the light sources. The fluorescent image system includes a monochromatic light source to generate white light by mixing red, green and blue monochromatic lights, and a fluorescent excitation light source for fluorescent images; and includes a mixed light source to provide a mixed light which mixes monochromatic light and fluorescent light, and an image photographing device which separates the wavelengths of visible light and fluorescent light in the mixed light, and photographs a general image, fluorescent image and mixed image.

Abstract: A method and system for optimizing a match between the color of an in-line part manufactured by a plastic product production machine and the color of a reference part by adjusting the concentration of masterbatch in the mixture of raw material fed to the plastic product production machine. The optimization of the color is based on spectra of the in-line part and reference part obtained within a short time interval using the same spectrometer, thereby eliminating the requirement for high accuracy spectrometer calibration and allowing the method, which determines the rates at which the base masterbatches are added to the raw material, to be carried out in real time on the manufacturing floor while the plastic product production machine is being operated to manufacture in-line parts.

Abstract: An electronic device may be provided with a color sensing ambient light sensor. The color sensing ambient light sensor may measure the color of ambient light. Control circuitry in the electronic device may use information from the color sensing ambient light sensor in adjusting a display in the electronic device or taking other action. The color sensing ambient light sensor may have light detectors with different spectral responses. A test system may be used to calibrate the color sensing light sensor. The test system may have a tunable light source with light-emitting diodes that are turned on in sequence while gathering measured responses from the detectors. Numerical optimization techniques may be used to produce final versions of the spectral responses for the light detectors from the measured responses and corresponding calibration data that is stored in the electronic device.
