Abstract
An improved color sensor is provided having two sources of illumination, one source being modulated on and off while the other source remains on. Data taken while the modulated source is on is compared with data taken while the modulated source is off to compute the effective fluorescence of the sample. A corrected color spectrum can then be determined for a defined source.
