BousquetReadColour-measuring instruments and their calibration[Show abstract] [Hide abstract] ABSTRACT: The types of instruments used for colour measurement of self-luminous and surface colours, and the choices available for their optical design, are described. Guidelines are given for selection of measurement conditions appropriate to different measurement applications. The important steps in calibrating and verifying the performance of colour-measuring instruments are described and the standards available for these procedures are discussed in detail.

Uncertainties are also required for establishing the traceability of a measurement to a national metrology institute. A systematic, analytical approach to uncertainty anal

COLORIMETRY The human eye has three types of color sensors known as red, green and blue cone cells which work together through the brain to give the perception of all colors. In the late 1920s William Wright and John https://www.researchgate.net/publication/44052101_Errors_in_colorimetry_caused_by_the_measuring_instrument Guild performed meticulous testing with groups of healthy young adults to determine the spectral responses of these three types of cone cells. In 1931 the C.I.E. (International Committee on Illumination) adopted these data as the CIE color-matching functions and defined the CIE 1931 XYZ color space. This work was so http://www.colorimetryresearch.com/learning/FCMM well performed that results remain essentially unchanged to the present day. Changes include interpolation of the original five nanometer data to one nanometer, and the addition of responses to low level illumination. WHAT A TRISTIMULUS COLORIMETER SHOULD DO The goal of any tristimulus colorimeter is to measure a light source or display with responses matching the three CIE color-matching functions [x(λ), y(λ), z(λ)]. In order to do this the colorimeter typically employs some form of filter/detector combination. These may have either a single detector with sequentially applied filters or multiple detectors with filters. Filtering detector response to match the CIE color-matching functions is difficult. In fact, most commercial tristimulus colorimeters, including two dimensional colorimeters, have significant detector/filter f1' errors. Measurement results can be reasonably accurate when the colors are broadband as those derived from pigments and dyes (i.e., paints, fabrics or incandescent displays) because colorimeters are typically cal

Meas Tech (1997) 40: 71. doi:10.1007/BF02505169 121 Views AbstractMethods of reducing the errors in measuring the chromaticity coordinates of objects using a three-channel photoelectric colorimeter and automatic recognition of the type of error in light source, with an appropriate zonal correction of the colorimeter readings, are considered. It is shown that the proposed methods enable the error in measuring the chromaticity coordinates of light sources to be reduced several-fold.Translated from Izmeritel'naya Tekhnika, No. 1, pp. 48–51, January, error in colorimeter 1997.References1.V.
