Abstract: A method and system for effecting an appearance model correction for a display unit, e.g., a CRT, using a polynomial-based algorithm is described. The correction may be effected in real time and is based on gamma values associated with the display. Strong correlations with the CIECAM02 specification are achieved according to the present disclosure. The correction functionality may be inaplemented using a colorimeter that includes a plurality of sensors/filter systems with non overlappng spectral responses, adequate for providing data capable of translation into standard coordinates system such as, CIE XYZ, CIE L* a* b*, or CIE Luv, as well as non-standard operable coordinate systems. The field of view of the colorimeter is chosen to closely track the response of the human eye using an optical path configured to select and limit the field of view in a manner that is insensitive to placement of the colorimeter on the source image. The optical path from the source image to the sensor is configured to select preferred light rays while rejecting undesirable light rays to maximize the signal/noise ratio. A rearward facing sensor channel is included to simultaneously measure ambient light impinging on the source image and feedback means to provide status and/or change of information.

Abstract: Un système permettant de mesurer la qualité des couleurs sur des objets arrondis est décrit. Un support (18) comprend un mandrin (24) servant à maintenir l'objet en une position fixe. Le mandrin (24) comprend de préférence un élément expansible en forme de vessie (38) monté rotatif sur un axe (40). Le support (18) comprend un réflectomètre (10) qui lui est accouplé de façon à permettre un déplacement angulaire dans un plan fixe. La boîte métallique est serrée en une position fixe entre le mandrin (24) et le réflectomètre (10) de façon que le densitomètre soit placé selon une orientation radiale fixe par rapport à la surface de l'objet. Différents points sur la surface de l'objet peuvent être mesurés par la rotation et la translation de l'objet et/ou du réflectomètre (10). La commande du positionnement de l'objet en rotation et translation peut s'effectuer automatiquement.

Abstract: The present invention relates to a color detection device for fabric dyeing machines, comprising a measurement chamber (2), ray emitting device (7), ray receiving device (8) with a chamber inlet (3) and chamber (4) outlet. The both ends of said measurement chamber have lenses (5A & 5B), in which the light ray emitted from said ray emitting device pierces through the lens (5A), the liquor in measurement chamber and lens (5B). The ray is received by ray receiving device (8). A filter (16) is placed in front of chamber inlet (3), a controller (15) connects to the ray emitting device (8), chamber inlet valve (27), chamber outlet valve (29) and cleansing valve (28). The invention could precisely detect dye liquor color in special working environment of dyeing industry.

Abstract: An optical fluid analyzer tool may have an evaluation flowline which receives a flow of fluid from a geotechnical formation and may have a cleanup flowline which receives another flow of fluid from the geotechnical formation. A flow routing system may be connected to the evaluation flowline and may be connected to the cleanup flowline. The flow routing system may establish isolated flow or commingled flow for the evaluation flowline and may establish isolated flow or commingled flow for the cleanup flowline. A sample chamber may be connected to the evaluation flowline and may be connected to the cleanup flowline. A first pump module may draw the fluid from the geotechnical formation, and an optical fluid analyzer connected to the cleanup flowline and the evaluation flowline may analyze the fluid.

Abstract: A light emitter (11) emits light with a plurality of wavelengths towards a test obj ect (3) held in a spectrophotometer tool (2). A light receiver (13) receives the light passing through the test object (3). A detector (14) detects absorbances of wavelength components from the light received. An optical path length calculator (16) compares, in the absorbances of the wavelength components detected, a wavelength component absorbance of light absorbed by a pigment that absorbs light with a wavelength other than a wavelength of light absorbed by an analyte in the test object (3) and a predetermined value of the wavelength component absorbance to calculate an optical path length. A corrector (17) corrects the wavelength component absorbance detected excluding the wavelength of the light absorbed by the pigment using the optical path length calculated by the calculator (16) to calculate a corrected wavelength component absorbance in a reference optical length.
