    Abstract: A portable colorimeter for characterizing the optical properties of a colored surface and in particular a colored surface containing metallic or pearlescent particles, which employs three multiangular spectrophotometric measurements to derive color constants for the surface. The colorimeter is a compact integrated unit housing irradiation, detection, control, analysis and display means and employs three illumination angles, preferably -30°, O°, and 65°, and one detection angle, preferably 45°, all measured from the sample normal. The method includes determining the tristimulus values of the color of the sample surface from low resolution spectral reflectance data preferably using twelve detector elements.

    Abstract: An image processing apparatus, an image reading apparatus, and an image forming apparatus are provided to enable a spectral reflectance estimation function with various characteristics to be determined selectively if the coefficients of predetermined instinct vectors are determined, thereby reducing the amount of data indicating a spectral reflectance. An operating method for an image forming apparatus comprises the following steps of: allowing an image reading unit to radiate a first light source on a photographed object to perform first scanning(S11); allowing a control unit to generate first image data(S12); allowing the image reading unit to radiate a second light source on the photographed object to perform second scanning(S13); allowing the control unit to generate second image data(S14); allowing the image processing unit to calculate a spectral reflectance for each pixel composing image data(S15); allowing the image processing unit to calculate incentive values in an XYZ color chart for each of pixels of the first and second image data(S16); allowing the image processing unit to calculate coefficients for obtaining a spectral reflectance estimation function(S17); allowing the image processing unit to determine the color and amount of toner(S18); allowing the control unit to supply image data to an image forming unit(S19); and allowing the image forming unit to form an image on a recording sheet using plural toners on the basis of the image data(S20).

    Abstract: PURPOSE: A measuring device for a color distribution of an optical fiber is provided to precisely measure the color distribution for the short optical fiber by using an optical fine distance measuring function and a fourie spectroscopy. CONSTITUTION: A beam generated from a light source(110) is divided into first and second optical signals by a first direction binder(115). The first signal is supplied to an optical collimator element(120-1) in a first collimator unit(120), and the second signal penetrates an optical fiber(135). The first signal passes through a scan system for being transferred to an optical fiber polarization adjuster(130) by passing through a first optical fiber collimator element(125-1) in a second optical fiber collimator unit(125). Thus, the optical signals are combined by a third direction binder(140). A first optical detector(145) measures an interference pattern data for transferring to a computer(155) through a low pass filter(150). A second direction binder(175) combines first and second helium-neon optical signals for transferring to a second optical detector(185). Thus, the second optical detector measures an interference pattern data from the helium-neon optical signal. Then, the computer measures the color distribution of the optical fiber by using the interference pattern data.
