22、for which international harmony requires such unique definition. CIE Standards are therefore a primary source of internationally accepted and agreed data, which can be taken, essentially unaltered, into universal standard systems. This International Standard has been prepared by CIE Technical Commit
23、tee 1-53*, “A standard method for assessing the quality of daylight simulators“, and was approved by the National Committees of the CIE. Observed colours of objects depend on the illumination of the objects and the results of colour measurements may depend on the illumination used in the measurement
24、. The CIE has standardized the spectral power distributions of several phases of daylight for use in observing and measuring colour. For practical applications in colour technology, illuminators are designed to illuminate specimens with light simulating one or more of these CIE illuminants. The accu
25、racy of simulation has an important bearing on the accuracy of visual matches and colour measurements. CIE Technical Committee TC1.3 studied methods of assessing the spectral quality of daylight simulators and issued recommendations in the publication: CIE 51-1981 A method for assessing the quality
26、of daylight simulators for colorimetry. That publication established the limits of the deviation from the ideal colour that initially qualified a simulator for consideration and established a test method to assign quality grades to simulators. The limits and test method expressed in that publication
27、 have been used throughout the world, since 1981. The historical development of the methodology is described in that publication. This standard is based on the principles and methods described in CIE 51-1981. There are several new features, based on recent research and standardization (JIS, 2000; Mc
28、Camy, 1996 and 1999). CIE 51-1981 treated CIE Illuminants D55, and D75 as well as CIE standard illuminant D65. CIE illuminant D50, which is widely used in photographic and colour printing technologies, was included in a later supplement to CIE 51-1981 (CIE 135/3-1999 Visual metamers for assessing th
29、e quality of CIE illuminant D50) and is also included in this standard. CIE 51.2-1999 includes both the original publication and the supplement. CIE 51.2- 1999 specified limits on colour deviation graphically; this standard specifies the same limits numerically. CIE 51.2-1999 listed wavelength-depen
30、dent constants for visible-range assessment over the wavelength range from 400 nm to 700 nm; this standard lists those constants over the range from 380 nm to 780 nm. The constants and wavelength range for ultraviolet-range assessment in CIE 51.2-1999 are retained in this standard. For the special p
31、urpose of ultraviolet-range assessment, the wavelength range from 400 nm to 700 nm adequately represents the visible spectrum, because all of the fluorescence emission considered is within that range. * Chairman of this TC was C.

36、1 INTRODUCTION The purpose of this assessment is to quantify the suitability of the spectral irradiance distribution of a practical simulator of CIE daylight illuminant D50, D55, D75 or CIE standard daylight illuminant D65 for the visual appraisal or measurement of colours of fluorescent or non-fluo
37、rescent specimens. The basis for the assessment is the special metamerism index for change in illuminant, using pairs of virtual (rather than real) specimens specified by their reflecting and fluorescing properties. The pairs of specimens are metameric matches under the CIE daylight illuminant, when
38、 evaluated with the CIE 1964 standard colorimetric observer. The method described in this standard quantifies the mismatch when the pairs of virtual specimens are illuminated by the simulator under test and evaluated by the same standard observer. A visible range metamerism index is derived to quant
39、ify the suitability of the simulator for the visible wavelength range. An ultraviolet range metamerism index is derived, using a different set of virtual metameric pairs, each pair having a fluorescent and a non-fluorescent specimen, which spectrally match for the CIE daylight illuminant and standar
40、d colorimetric observer. The non- fluorescent specimen in each pair is specified by its spectral radiance factor. The fluorescent specimen in each pair is specified by its spectral reflected radiance factor, relative spectral distribution of radiance due to fluorescence, and spectral external radian
41、t efficiency of the fluorescent specimen. The ultraviolet range metamerism index quantifies the mismatch due to fluorescence resulting from the use of the simulator and the standard observer. 1. SCOPE This International Standard specifies a method of assessing the spectral quality of the irradiance
42、provided by a daylight simulator to be used for visual appraisal of colours or for colour measurements and a method of assigning a quality grade to the simulator. It specifies the maximum permissible deviation of the chromaticity of the simulator from the chromaticity of the CIE standard daylight il
43、luminant or CIE daylight illuminant being simulated, for a simulator to be graded by this method. 2.
