How do Spectroradiometers measure light?
The visible band “rainbow” of light falling on the sensor is converted to electrical signals which are captured, corrected, processed, and reported as an array of radiance values and derived colorimetric results.
The CIE XYZ values are computed from the full array of spectral data using precision math functions (standard tri-stimulus integrals) prescribed by the CIE.
