Abstract
A system comprises two or more light sources comprising a first light source and a second light source, each light source of the two or more light sources configured to provide light of a particular wavelength, wherein a first wavelength of a first light provided by the first light source differs from a second wavelength of a second light provided by the second light source, and wherein the first light has a first radiant energy that experiences roll-off. The system further comprises a controller configured to modulate an attribute of each light source to compensate for the roll-off, the modulation comprising modulating an attribute of the first light source, and the modulation further comprising modulating an attribute of the second light source, the modulation of the second attribute being different from the modulation of the first attribute.
