Abstract
Feedback control of a spatially distributed light source for a light integrating cavity in which the light acceptance angle of the light feedback device is expanded by means of a light diffuser at the feedback port so as to better average the localized light intensity variations on the internal surface area of the cavity caused by arc wander in the spatially distributed light source.
