By configuring the oscillating mirror speed to 19 Hz, a raster for recording and reading
quickly moving objects can be reproduced.
The oscillating angles are selected in the software. The minimum and maximum
values are –2.5° and +37.5° respectively.
The scanner can be tilted so that the software setting of 17.5° lies on the horizontal
as a 0° reference.

These models have a higher read rate (1200 read processes/second) than the
standard models, which is not influenced by the oscillating mirror.
The following example shows a setting of +10° for the lower line and an angle of +20°
for the upper line (see figure below).

The number of scans on a given reading area can be increased by
limiting the raster width to the required minimum.
