10.5 Raster Tuning

Raster tuning refers to tuning the servo drive to have constant velocity over a wide angle
and then have the ability to "fly" back to its start of scan location. A typical raster
command input waveform is a saw tooth waveform. The important parameters are the
frequency (Hz) of the waveform, the desired fly back time and the velocity linearity of
the active scan. A triangle waveform produces a bi-directional raster scan with no fly
back. Typical applications are film imaging, metrology, fluorescent microscopy and
laser TV projection.
