Fiber optic systems for colorimetry and scattered colorimetry
SPIE Proceedings, 2005An innovative series of optical fiber sensors based on spectroscopic interrogation is presented. The sensors are customdesigned for a wide range of applications, including gasoline colorimetry, chromium monitoring of sewage, museum lighting control, for use with a platform for interrogating an array of absorption-based chemical sensors, as well as for ...

Colorimetry by Abridged Spectrophotometry
Journal of the Optical Society of America, 1949It seems to be generally conceded that the results obtained with a photoelectric colorimeter are significant only when the spectral characteristics of the sample and standard are similar. When this is the case, the selected ordinate method of integrating spectrophotometric data can be greatly abridged, a single selected ordinate being adequate under ...

We analyze the sources of error in specifying color in CRT displays. These include errors inherent in the use of the color matching functions of the CIE 1931 standard observer when only colorimetric, not radiometric, calibrations are available. We provide transformation coefficients that prove to correct the deficiencies of this observer very well.

In order to be able to compare bronze paints with ordinary standards such as Munsell papers, it is necessary to establish conditions of illumination and viewing which will render the metallic reflection inconspicuous. It has been found that completely diffuse illumination and normal viewing are highly satisfactory, and a small integrating sphere has ...

Colorimetry by a New Principle
Archives of Ophthalmology, 1978A simple and informative method is described for determining the type and extent of color defects. The subjects' responses are registered automatically on a chromaticity diagram that is based on the newtonian model. Color defects are readily identifiable by a skewing of the normal central gray area toward the defectively perceived color.

Colorimetry, the science of quantitvely describing color, is essential for color reproduction technology. This is because it creates standards by which to measure color, using mathematical techniques and software to ensure fidelity across media, allow accurate color mixing, and to develop color optimization.

We consider the structure of colorimetry, essentially of Grasmann’s threedimensional linear space that summarized metamery (confusion of spectral distributions) for the human observer. We show that the definition of an orthonormal basis for this space requires a scalar product in both the space of physical beams, and the representation space on which ...

The Colorimetry of Whites [PDF]
Journal of the Society of Dyers and Colourists, 1968 The inadequacy of the CIE (1931) Standard Observer for the comparison of near whites is discussed, and the adaptation of the Harrison colorimeter to obviate this difficulty is described. Greater instrumental sensitivity is achieved and measurements agree well with visual observation when whites that vary in a regular manner are compared.

Matrix Techniques in Colorimetry
Optometry and Vision Science, 1980The usual (geometric) procedure to determine the chromaticity coordinates of a color that results from the additive mixture of colored stimuli is to plot the coordinates of these stimuli on the CIE chromaticity diagram and apply the center-of-gravity rule.

Journal of the American Ceramic Society, 1952
Some color characteristics of ceramic glazes that are important in industrial design and specification are described in terms of the fundamental parameters of colorimetry. Algebraic expressions are developed to relate the spectral reflectance of a specularly transmitting glaze on an opaque bisque with the glaze thickness, interfacial reflectance ...
