Abstract
A method to adjust the energy transmitted from a multiplicity of light sources to provide an adequate reference for spectral measurement or control using a multichannel feedback adjustment algorithm that compensates for the interactions between adjacent spectral ranges and sets reference light sources for optimal system performance using a normalized energy value for each spectral range is disclosed.
