REMOTE DEVICE FOR MEASURING COLOR COORDINATES, CHROMATICITY, AND COLOR DIFFERENCES

This paper describes a remote device based on a calculational method f or obtaining colorimetric quantities from the measured spectral reflec tances of an object. The time to measure a single spectrum is 3.2 ms. It makes it possible to determine the colorimetric quantities of not o nly self-luminous but also nonself-luminous objects illuminated by a s ource of any unknown spectral content. A built-in microprocessor avera ges over sixty-four spectra and computes the colorimetric quantities.
