Abstract

In this paper we demonstrate that the amplitude and phase of the principle eigenfunction for the pupil-plane mutual intensity can be used to specify a beam that concentrates its intensity at the brightest point on the target in a target-in-the-loop system with a spatially incoherent reflected field. In addition, we discuss two methods for beam control: a method for which the beam amplitude and phase are determined as the principle eigenfunction for the measured (but incomplete) pupil-plane mutual intensity; and a method for which the beam amplitude and phase are determined to maximize a window-based image-plane sharpness measure. We demonstrate that the two methods are similar, and that both result in beams that correspond to the principle eigenfunction for an apodized mutual intensity function.
