Abstract
The technology disclosed relates to improved acousto-optic deflectors (AODs). In particular, it relates to compensation for subtle effects not previously addressed by AOD designers. A shifting center of gravity is described and addressed using advanced power equalization strategies. Denser writing brushes are provided by using a two-dimensional array of beams with corrections for factors such as angle of incidence at the AOD interface.
