Describes two methods: the first method uses a spectroradiometer, which gives a spectral energy distribution of the light source being measured from which the chromaticity can be calculated: the second method uses the tristimulus colorimeter, which employs a combination of a photosensitive device and a filter to reproduce the distribution of spectral tristimulus values for the appropriate field angle. Decrit deux methodes: la premiere emploie un spectroradiometre qui donne une repartition energetique spectrale de la source de lumiere mesuree permettant de calculer la chromaticite la deuxieme methode emploie un colorimetre trichromatique qui comprend une combinaison photodetecteur-filtre servant a reproduire la distribution des valeurs trichromatiques spectrales de langle de champ approprie.
