FastSCAN 51
object’s surface during scanning, but no closer than 80 mm to keep within the
camera’s field of view. If you are using the Receiver, parts of the surface closer
to it will scan more accurately. Try to keep the Transmitter close to the Wand
and Receiver, as accuracy deteriorates with distance, but no closer than 100 mm
to avoid signal overload. The maximum separation of any two components is
about 750 mm, but for best results, keep them as close as possible.
Q. When I generate a Basic Surface, it has “bumpy” or “crystalline” patches—what
is wrong?
A. Successive sweeps over the same part of the surface have not merged properly.
Try using Edit/Register Sweeps (Section 5.3). If the result is still unsatisfactory
you may need to repeat the scan.
Q. How far away do I have to keep metal objects from the scanner?
A. The presence of metal objects while scanning interferes with the tracking of the
Wand and degrades performance. As long as you keep any large metal objects
at least 1 m from the Wand, the Transmitter, and the object you are scanning,
they should not pose a problem.
