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.

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 ...

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.

In this study, a rapid, stable, and sensitive colorimetric/surface-enhanced Raman spectroscopy (SERS) method was developed based on a polyvinyl alcohol‐decorated Au nanoparticle (PVA–Au) colloid for thein situ detection of thiram residues in fruits and ...

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.

Microcystins, the lethal cyanotoxins from Microcystis aeruginosa, can inhibit the activity of protein phosphatase and promote liver tumors. Herein, a dual-modal split-type immunosensor was constructed to detect microcystin-LR (MC-LR), based on the ...

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.
