A two-dimensional scanner employs first and second pivotable mirrors (36 and 40) to control the position of the target point that a light spot assumes in a target phase (44). The second mirror (40) is driven in a resonant mode. An fx theta lens (42) converts the pincushion error that would otherwise result into a barreling error, which can be compensated for by controlling the amplitude of the second-mirror oscillations.
