Principles of Light & Color Measurement
Scientific methods allow us to understand and quantify our perception of visible light and color. Learn the language of light, including visual definitions of luminance, illuminance, luminous intensity, and luminous flux. Understand the anatomy of the CIE chromaticity diagram, including spectral locus, Planckian locus, dominant wavelength, and purity. Derive color values using the CIE 1931 and CIE 1976 color spaces and CIE Color Matching Functions. This tool is a useful reference for anyone with a passion for light metrology, or who works in applications dealing with light & color measurement.
