METHOD AND DEVICE SCANNING A TWO-DIMENSIONAL BRUSH THROUGH AN ACOUSTO-OPTIC DEFLECTOR (AOD) HAVING AN EXTENDED FIELD IN A SCANNING DIRECTION

摘要

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 equalisation strategies.
