Definition
There are two kinds of modern colorimeters: one that includes and one that excludes a light source for measuring the surface or a self-luminous stimulus respectively. Both types of colorimeter measure International Commission on Illumination (CIE) tristimulus values under particular illuminant and observer conditions, e.g., D50/2°. The instruments are applied to measure a test stimulus displayed on a monitor, printer or a light stimulus. CIE International Lighting Vocabulary [1] defines the colorimeter as an instrument for measuring colorimetric quantities, such as the tristimulus values of a color stimulus.
Overview
The colorimeter measures XYZ values in a luminance unit. This overview is divided into four sections: optical structure, measurement geometry, spectral responsivity and measuring uncertainty, and applications [1] (Photodetectors).
Optical Structure
The structure of the colorimeter can be divided into two parts: the...
