Crosstalk between a drive coil and a primary feedback coil is eliminated
by positioning a secondary feedback coil in proximity with the drive coil
for contamination by the crosstalk to the same extent as the primary
feedback coil, and by processing feedback signals generated by the
feedback coils to cancel the crosstalk. The drive coil is used to
oscillate a scan mirror employed in an image projection arrangement or an
electro-optical reader.
